If the problem is still not resolved, the Print Head may be damaged.

Do not disconnect the power plug when turning off the power. When you have performed the procedure until step 3 and the problem has not been resolved, turn off the power and clean the Print Head deeply again after 24 hours. If the problem is not resolved after cleaning the Print Head twice:

If there are missing lines or horizontal white streaks in the pattern: When the Print Results Are Blurred or Uneven:Īfter cleaning the Print Head, print and examine the nozzle check pattern. Increasing the print quality in the printer driver settings may improve the print result. Open the Scanning Unit (Cover) and make sure that all lamps on the ink tanks are lit red.

Make sure that the orange protective tape does not remain on the ink tank. This can cause trouble with the Print Head and ink tanks. If printed ruled lines are misaligned or print results are otherwise unsatisfactory, aligning the Print Head may improve print quality.ĭo not rinse or wipe the Print Head and ink tanks. Follow the procedure below to print the nozzle check pattern, check the print head nozzle condition, then clean the Print Head. If print results are blurred or colors are not printed correctly, the print head nozzles are probably clogged. I think I now have to take it back to the shop - if / when I know more, I will post it here. So it looks like harrymc is correct: there is simply a hardware problem. Update: inside the print head cradle (which you insert as part of the set up process), I can now see wet ink on the cartridge side but no wet ink on the side which touches the paper. Just to be clear: it gives every impression of printing (paper goes through, it sounds like the printer heads are moving, prints only on command) but the output is blank pages. Printer cartridges are correctly in place (red light showing for each) and all protective orange plastic bits and tape removed: the foam part of the cartridge (underneath) is exposed and the L-shaped air hole (top) is open. The result is the same when I use a different (also Vista) computer. Whether I print or copy, the result is the same: blank pages. I have a Canon MX870 printer which I have connected to a Windows Vista laptop via a USB connection.
