Why printing runs at third page - Tally Line Matrix T6090 Printer

Did the machine state to replace the drum and developing unit are they OEM or third party? Did you run gradation?

Well you can start be cleaning the drums and adjusting the paper tray, if the printer is under warranty then get it checked. There was no recall for this printer, doesn't say that on hp website.
In case of any questions kindly revert.
Thanks. If this was helpful, then kindly rate me.

Go to start>>>Control Panel>>>Printers.
Make a right click on Printer Icon select Properties.
Go to Advance Tab.
And make sure that Print directly to printer is unchecked.

Align the print cartridge once more, from printer properties and print a test page. See if still that problem persist.

Go to Printers and Faxes.
Right click on the printer and select Properties.
Toward the bottom, click on Printing Preferences...
Click on the Support tab.
Click on Print Settings.

This should give you three pages. The third page has the network settings including Ethernet/MAC address.

My printer started working right again when i completely unpluged it for 5 min.and rebooted all the printing software

you need to check the print property to be selected as ALL instaed of selection. by clicking on file menu >print>check the box ALL to print the whole pages

sounds like your print heads need calibration..run that, and do a test page.

My HP Deskjet F2100 All-in-One series printer worked up until today. It printed three sheets and then stopped.
