Printer:
CP3505 512MB RAM
Problem:
Printer does not appear to print yellow on photographs. We print a lot of documents with text and photographs in. Everything is great - text is crisp and clear, no streaking, blurring or marks. The only problem is with photos - they seem to be lacking yellow. Printing yellow as text, or blocks of colour on standard graphics, works perfectly.
Tried so far:
1) Replaced the yellow cart a number of times. Sometimes it works for a while, then the problem returns.
2) Called an engineer to fix - useless! Recommended a main board replacement, which was done, to no avail. Money refunded from engineer's company, but still left with an unneeded main board!
3) Updated drivers - all drivers available have been tried. Currently using very latest PS driver.
4) Run PQ diagnostics regularly - shows no fault with the yellow cart. The green/yellow and yellow/green test page prints perfectly, as does the final mixed colour test page.
5) Tried swapping the carts (yellow/cyan) and attempting a test print, but the printer won't allow it. Tried to disable cart checking in diagnostics menu, but won't allow that either.
6) Using genuine HP yellow cart.
The main computer that holds the print queue is running XP, however the error is generated from any computer. This includes one running Ubuntu 12.10.
Can anyone offer help or advice?
Cheers,
Adam
