Extra horizontal black lines

[airfish1]

The printer was working fine. Since some days I have extra black lines with a spacing of about 27mm on some pages – see image. I have changed already the black ink cartridge and done all the suggested tasks like cleaning print heads, etc..

Any ideas what could be the issue?

What about internal printer pages from the printers menu do they have those lines too. This could be something driver/computer related.

A copy produced by the printer shows similar lines  (no lines on the original page!). On the status-page there are less lines.

It could be that some amount of dirt is on the printhead and it's leaving (scraping) marks on the paper.

Use some texts software to write a few words in red print it if you have black lines clean the printer, if there are no lines when printing in red only then your printhead failed.

Ok – there are no black lines when printing the text in red, blue or yellow.

Back in b/w mode there now nearly no extra lines – meaning there could be some amount of dirt on the printhead as expected by you.

How could I clean the printhead manually – cleaning with the maintenance tool I have done already twice. Is it possible to change the printhead myself – or does it make no sense for a 5 year old printer?

If there are no lines when printing in red, that makes your printhead start failing.

Ok - I will look for a new printer in the near future.

Many thanks for your support.
