HP 3800 Color LJ Prints 2 black lines. Pic Included

Hi,
I have a HP Color LaserJet 3800. Since last summer it has been printing 2 black horizontal lines across every page. They are always in the same spot, so I'm thinking it is just something that needs to get cleaned and have ruled out the cartridges. (They have all been replaced multiple times since the issue first started). This happends with and without using the duplexer.
I took out the fuser? I think that's what it's called from under the front cover (It was really hot) and cleaned it with a moist papertowl, but that did not make any difference.
Any suggestions on what to clean or where the parts are located? I'm a noob when it comes to working on printers, so a step by step/diagram/pictures will be the best way to explain,
Here is a picture of what the pages look like, I have circled the black lines:

Scratch that, I looked at the manual and found how to open a part to fix a paper jam. There were two rollers in there that fit perfectly with the lines. I cleaned them up and now no more black lines.
Fyi, to get at the rollers I had to open the front of the printer, then on the bottom of the inside are 2 green tabs. I pressed them and lifted up the plastic piece to reveal these rollers.

HPLJ 4250 printing black line inch size across top of page.

HPLJ 4250 printing black line inch size across top of page. The Maintenance Kit and the toner have been changed, the option in the menu to clean fuser has also been done. The black line is intermittent so it hard to work out what to do next.

Thanks for the tip Mikey - however the same thing happens with the thin black lines when I print on 'normal' A3 paper too. On normal A4 paper it's fine, no lines, but when I print to A3 I get the lines - on both kinds of paper.
I've attached a couple of (awful-looking) scans to help illustrate my point.

Laserjet 500 color consuming color toner printing black and white text

How can I prevent the consumption of color toner when printing black/white text documents (pdf in Adobe Acrobat)???
I just finished printing about 2200 2-sided pages in Adobe Acrobat pdf files, all black/white text, on my 500dn. The color toner appears to have been consumed as I am getting signals that my yellow and magenta are below 10%. They were over 40% when I started the project.

Problem printing color only prints Black

My printer does not print the colors it shows in the display that they in and installed correctly but do not print out on the info page .It only prints out black.Example if I print a coupon the stuff on it that is in color is just blank

Hello @Big_Show,
Welcome to the HP Support Forums!
I understand that you're not able to print in colour when printing to your HP Officejet 6500A Plus e-All-in-One Printer from your Ipad. I would like to assist you today with resolving this issue. First, I'm going to have you run a test to verify if this is a printer issue or a driver setting issue.
Step 1: Print a Print Quality Diagnostics Report:
1. Load letter or A4, unused, plain white paper into the input tray
2. On the printer control panel, touch the Right Arrow () to display the second navigation screen
3. Touch the Setup icon (). The Setup Menu displays.
4. Touch the Down Arrow (), and then touch Reports.
5. Touch Print Quality Report. The print quality report prints.
If this report prints perfectly, than your colour printing issue is due to a setting conflict on your Ipad. On your Ipad can you open Safari and go to www.google.com. When the Google page shows, try to print that to verify if colours are printing from your Ipad or not. If the colour printing issue is only affecting coupons, than this is most likely a security feature. There generally is specific coupon apps that you can download that support coupon printing.
If this report prints with no colours, than you are experiencing a hardware print system issue. Can you please click here and run through the print quality troubleshooting steps provided.
Please let me know if the steps I've provided resolve your colour printing issue. Should you still be experiencing colour print issues be sure to let me know how your Print Quality Diagnostic Report printed. I look forward to hearing from you!

Colored Background Printing Black

I'm completely new to Photoshop since Christmas. I've created a wedding invitation design and it looks great on the computer. However, when I print the file (saving it both as a .pdf and as a .jpg), everything I have set to a couple different shades of blue prints in a grayscale. All of my greens come out perfectly. I have adjusted and tried to lighten blues, but I keep getting black and gray. Please help...I'm nearing the time where if I can't get this figured out, I'm going to be forced to order invitations...I'd rather do it myself:-) Here's what the file looks like:

Hi,
I think you can try selecting the option 'Always optimize for Printing' radio-button from the Color Settings dialog which opens on clicking Edit >> Color Settings.
Take a test print and see if some difference happens?
Thanks

COLOR BLENDING IS NOT SMOOTH (pic included)

I'm having problems with camera raw. The colors aren't blending smoothly. I can't even describe what the problem is very well, it's best to look at the picture. PLEASE HELP! :D
http://s3.photobucket.com/albums/y91/Liz217_/?action=view&current=HELP.jpg

It's likely that the LUT for your video board has a bend in it. If you are
able, start by changing your monitor profile to a generic profile from the
monitor, or if one is not available, sRGB. If that improves the
appearance, you probably need to use a different profile.
In the interests of speeding things along, I'll guess that you are
calibrating your monitor with a device like the Spyder or i1.
One likely cause for banding would calibrating the monitor to a non-native
white point. Do another calibration, specifying native white point.
If you are seeing a purple band in the blue sky, I have another suggestion.

Why doe's my 8500A printer use color ink when printing black and also when unit is cleaning

I only print in black. I am required to buy all the colors because my printer will not operate when any cartridge is empty.
I was informed at Office Depot that all printers operate this way. According to them it also uses ink when it goes through
the cleaning cycle.
The XL ink package at Office Depot (black, yellow, cyan, magenta) is $97.00 + tax.
I hope someone has a logical answer why this is set up this way.
Why do I need colors to print black?

The 8500A takes 4 ink cartridges and 2 printheads (one for black/yellow, and another for the other two colors). This design is so that you have have larger ink cartridges (stationary on the side, the printer only moves the printhead during printing). A drawback is, you have to have all the cartridges in, without the ink cartridges, the printheads could be damaged and would cost more to replace.
Printing black text uses black ink only, it does not use color ink. The "Clean printhead" function does print a color page and uses color ink, but you only need to do this when you notice lines missing (printhead clogged) in the printout.
If you print mostly black only, choose a model that uses cartridges that has a printhead built in. These printers typically can still print black with color ink out.

Black line drawings print as purple at certain areas

Hi,
We have a HP designjet 110 plus in our office as a network printer. We have been experiencing some problems when we print black line drawings. Several parts of the drawing will print as purple instead of black (meaning a line/area of shade will be partly purple and partly black). The purplish areas are pretty much consistant through a single drawing, butwill be different from drawing to drawing. I have temporarily set the printer to print with black ink only, but the printing time doubles. Is there anyway to fix this problem? Thanks.

HP LaserJet CP1518 only printing black and white!

Here is a weird issue. Today, my HP color LaserJet will only print Pages documents in B&W! The document in question printed in color yesterday. I tried a new document, and that one printed B&W! I 'printed' to a PDF and in Preview it was color, but printed black & White!! I opened a Photoshop Document and that printed in color, so it seems to be with Pages. Again, the document printed fine yesterday.
I do have kids, and we thought they may have changed something, but if so, I can't seem to get it back!
Help...please........

Check that you have the HP selected in +Print > Printer.+
Next pull down the button/menu marked Layout to +Color Matching+. Then check that you do not have +Profile > Other Profiles… > Black & White+ selected.
Usually +Adobe RGB+ or Automatic is the one you want.

When I print a 4x6 color picture using an iMac with the latest operating system using a Canon MX892 printer, faint black lines appear every 3/16 of an inch. When I print the same picture using iPhoto there is no problem.

When I print a 4x6 color picture using an iMac with the latest operating system using a Canon MX892 printer, faint black lines appear every 3/16 of an inch. When I print the same picture using iPhoto there is no problem. Any suggestions?

What is the resolution of the picture that you are trying to print?
Go to Image>resize>image size, read the resolution in px/in, then report back, please.
Also, are you in a position to try printing with another printer in an attempt to narrow this down?

Officejet 6310 prints solid black line instead of text.

Good day. My officejet 6310 has started printing a 3/8" solid black line instead of text. I've replaced both color and black cartridges. I've also run align and clean cartridges. Does anyone have helpful suggestions?

This type of result is often due to errors in the HP printer drivers. Several things can be tried. Sometimes, using a tested driver for an older, but compatible printer will do the job. A lot of folks used the use the HPLJ2 driver even with HPLJ3 and 4 systems. Another option is to try to print as a graphic. At this point, I can only suggest playing around with things. A lot of folks like the graphic driver aspect instead.
You might also consider printing to the printer in a PS mode rather than PCL if that option is available.
I am only suggesting things I have seen tried by various folks. I don't have a good explanation.

Designjet T790 color printing poor line quality

Good Morning,
We have the HP Designjet T790 printer. Line quality is poor when printing color images (stepped and jagged). Line quality is ok when printing black only. I tried to change the settings to improve line quality and end up with a compressed, unuseable document. I ran all diagnostics available through the HP instructions. I was wondering if there is a different driver OR settings that I may try to improve my printer quality.
Thank you in advance.

Black line sketch renderings printing with teal or magenta

Aloha,
When I print architectural drawings with my DesignJet 110 I sometime place computer generated sketch renderings in with the architectural plans which are vector line drawings. The architectural line drawings and the sketch renders are computer generated made with ArchiCAD. The HP 110 DesignJet prints the rendering and only the rendering with teal or magenta or a fade of both even though the rendering is black lines. The architectural line drawings on the same page print beautifully in black. There is nothing on the page that is using any color lines.
When I set the printer to "Only Use Black Ink" the renders come out in black but the quality of the rendering's lines is poorer than when it prints using the teal/magenta.
I would like to get the printer to print high quality renderings with just black ink.
What is causing the problem?
How can I fix the problem?
Mahalo,
John

Printing to Canon S9000 Issue - Black Lines - Mac

All,
Having some issues (assume Driver) with printing from LR 2.3 and CS3 going to Canon S9000. Printing from Preview is fine. However iPhoto shows the same thing. I am getting evenly spaced (about 5mm apart) thin black lines when printing. It is consistent across different papers, including Canon Photo Paper Pro. I called Canon yesterday, and the fact that Preview works fine would seem to indicate something with the driver and Adobe and iPhoto. I'm not talking a microbanding. These are very distinct black lines. I've tried letting the printer manage the color, I've also tried using profile with the printer. I am using the most current BJ driver from the Canon site for the Mac (Leopard) and the printer.
Images from QImage on my Windows machine are also fine to the printer with I have it hooked up there.. Could use some help in debugging (hopefully without using up all the ink) :-)
Also getting occasional random "LR unexpected termination" message after printing.. One time happens, another doesn't.. No rhyme or reason I can see.
Update: Unexpected Termination seems to happen more often when stacking up a few prints in the print queue.
Jay S.

Even worse...
we have three machines updated today and the exact same problem on each of them:
Indesign CS3, Acrobat 8
Printing to Distillers Virtual Printer.
Previously Pages were PDF-ed in the format they had.
Now they are NOT - they all are on A4. The PDF-Options of Apple mess up the PDF-Options of Indesign. Apples PDF-Options do no longer ignore the pagesize, but overwrite the Indesign-Options.
This is a MAJOR bug for us, as any output into high-res-PDF for printing doesn't work via export, but via Printing to Distiller. This is a big big sucky thing, which Adobe or Apple will hopefully fix soon.
