Horizontal white stripes when printing.

[FM_-1-]

The printer (it was connected to the electrical network) was idle for about 4-5 days. Today I printed a page and saw white lines. How do I solve the problem? The printer is new, not even a month old. Cleaning cartridges, performed 6 times! The ink level is high.

UPD:

Another cleaning of the heads was performed in 3 stages, with a wait of about an hour after the last cleaning.

I turned off the MFP with the button on the case and disconnected the power cable. I waited 24 hours. Almost nothing new.
