Hi - I have a problem with my 1638 which just surfaced a day ago. When I do a test print the leading print of one head skips a major part of the black and yellow. Every time I do a head clean the problem is worse. Until now there is almost no black or yellow.. The other colours and the rest of the black and yellow prints are fine. The picture attached shows the effect. The first tests are at the bottom the most recent at the top.Any one any ideas?

I'm not familiar with this brand, but if they are anything like Roland's then it could be your dampers or cap tops need replacing.

What does the bottom of the head look like. To me that nozzle check looks like the head has physical damage.

A agree. Looks like physical damage to the nozzles. Cap top and dampers won't hurt especially if they are due for a replacement already.
Hi I agree it does look like physical damage, I have inspected the head and cannot see anything.
However, On the test print there are four blocks of yellow and black. Only one is affected.
I have printed from a file a strip of CMYK from each head separately - see photo - and it prints fine. It seems that only the nozzle check pattern is a problem.
I have tried shifting the paper along so that it prints from a different place on the carriage but get the same result on the black and yellow.
Any ideas?
