Problem with color on Oki c5100

Hi David,

HP Photsmart printer, work in TIJ (Thermal InkJet) technology, for printer to function; you need to have all 6 ink cartridges.

You have to determine if the drum cartridge or the fuser is the problem. Do a panic stop before the paper hits the fuser and see if it has the residual image. If it is clean then the fuser is the problem.

Open you printer and pull out the fuser assembly and look if the upper roller is fine because if it`s damaged it could lead to the double image.

By removing all the cartridges you'll find the belt. Replacing is very simple. Lift it out and put in the new one.

One or more of the drums may be defective. Swap the black with another color and print a document. If that color printed the charectors ok, then continue the test with the other drums each taking a turn in the Black drum position until you find the bad drum.

What has changed?

Is it possible that the color cartridge is empty?

Check the driver properties and make sure that the driver hasn't been changed to "Monochrome", "Grayscale" or Black and White.

Hmmmm.... Just a question, is it a brand new cartridge? If it is, it may be dried up.

FROM YOUR USEWR MANUAL>>>>>>>

In colour menu

AJUST REGISTRATION, press EXECUTE
Performs automatic colour registration
adjustment. Normally this is done on power
on and when the top cover is opened and
then closed. This process accurately aligns
the cyan, magenta and yellow images to the
black image.

Use oki drums and toners, clean led heads

Hi George,

It sound's like an ink-feed issue:

1) Dirty heads, even after cleaning
2) No-ink or poor quality ink
3) Damaged head: some are part of the cartridge, some are not
4) Air bubbles in ink

The test page is typically not as hi-res nor as saturated as a
photo print. The hi-res photo puts the greatest demand on the print head.

The color lines you see are actually lines of missing color,
where the head has failed to deposit ink, so one or two primary
colors are missing from the complete picture.

For example missing yellow will make a blue line.
Missing magenta will make a green line
Missing cyan will make a red line.... etc..

Clean the heads again and again, print again and again,
hoping to flush the system.

BUT, keep in mind that cleaning wastes huge amounts of
ink and tiny little cartridges of ink cost more than many new printers.

I need to know if the test page that the unit prints as "Demo Page" comes out fine. If this is the case, your problem is within your application (software) or computer connection (check all cables). If this is NOT the case, I'll need to know more about your scenario. Operating system, type of connection (USB, parallel) and what are you trying to print. I'll be waiting.
