Blank after one good page, then rapidly deteriorated.
No resolution of problem unfortunately. After three soakings of the print head, a B/W copy came through totally blank. I tried a colour copy, wondering if the problem was confined to the 4th channel (large black). Colours copied OK, but black areas were grey/streaky. I therefore replaced the large black cartridge with a fresh one, and tried a B/W run. Sadly, after two OK pages, rapidly deteriorated over the next four pages with fainter streaks, finally ending with a blank page. Any other ideas?
I'm obviously disappointed, particularly as I have urgent copying to do before a Choir rehearsal next Monday. Is there a UK supplier for the part? Although it says the part shown is for an MP630, it is clearly different from mine, with 7 channels rather than 5, so I am reluctant to order from Hong Kong, especially as it talks about 7-day delivery. Any thoughts?
