Half-way through a print job of a pdf with text and graphics it just stopped with the support code 7500, and saying 'Printer needs repair, switch off and unplug. See the manual, and contact a service centre. ' Is this fatal, terminal? I'm wondering if a service centre would even look at it, as...

Thank you all for your expert opinions, adn I shall keep my fingers crossed, but brace myself for adding htis printer to my pair of MG 5350s with the B200 error collecting dust in the corner.

So... I did a new nozzle check on clean paper, having set the output of ScanGear to be .png. And what do I get? A near-perfect (to my eyes) result, complete with Cyan bands as they should be. Bizarre! Here's the scan, and at 600dpi this time.

Thanks. It'll be a while before I get all that done, but I'll come back when I have something to report. OOI did you also do the photoshop analysis of the band that is supposed to be grey? I'd be interested to know what it says.

Scan attached. I took the cyan cart out and pressed the paper with the nozzle check against the wet pad, I then smeared the resulting very dark mark with a damp cotton bud. HTH

Title says it, really. Canon TS 6250 (European , if that matters.) Carts are PGI-580, CLI-581 Everyday document printing and I notice the colours are wrong, not blue enough. First thought was the cyan cart was empty/dry/faulty, so did a nozzle check. My prn [like many] does a grid of black with...

(I'm away for the weekend, I'll be back to bother you all again, no doubt!)

😇 😀 That accolade is safe with you guys! Thanks for the link to the manual, (and always good to have anyway). I'm thinking of doing some cleaning first, to absorb excess ink from the area. Is that pointless? (Knowing that disassembly is not going to be quick or easy.) Oh, and, is it bad to...

Thanks for the summary, correct - I think - in every way. The penultimate paragraph leaves me despondent, which is only slightly countered by the wish to succeed in order to fulfull the final line! However I feel unqualified to understand and master the electronics of the printhead, but I have a...

Thanks, will look through those.

they posted once, with a slightly vague description of which pins they covered, and never responded to further questions. I tried what I thought they had done, but it didn't work in my case. I can probably find the comment to a youtube vid if you want but all the information is abaov.e

I'm not sure what pissing up rope is, but since others /have/ regained colour printing by covering contacts, then I'd like to try the same - whichever contacts work for my printer, and having then having printed on 20 discs, I won't care that much if it keeps going or not. This job is a favour...

So, does anyone have any information on which contacts to cover to regain colour printing?

Thanks.

I'm a poor typist, and hate monospaced Courier text, so when I bought my Compuadd 286 pc and discovered HP's first Deskjet (in 1988?) I was very excited. :) ( It was slow, mono, and cost an arm and a leg [£600-800] , plus extra for the font cartridges!!) I've had a few since then, with Canon...
