My hp laser printer 1020 is printing extra lines

how could I manage the auto printing in laser jet 1020??How could I delete the past setting printing from it's propertise??

More than likely it is the TRANSFER roller which is made out of spongy rubber, wipe with a clean dry cloth.

Could you be low on toner? Shake the cartridge and try again.

It is not a laser problem, since it is factory sealed.

try with different tone cartridge and if its still give problem its can be problem with fusser assembly internal part which need to be serviced or replaced by service person

that happend to me once you need new ink cartereges or get a macanic in

try going on ur computer that the printer is contected to and have the printer align itself

You write "type the above line at command prompt". I dont't know Where exactly to write? Can you tell me!

I loss the drivers of HP LaserJet 1020 printer. I need now. Please help me.

try to see if the printer will print anything by opening and closing the top door that leads into the toner seven times just open and close, if the printer prints a paper with lines then the printer is working now if the printer doesnt then try to take out the ink, paper and unplug the power cord and let the printer set for about three minutes..
If the printer does prints now it up to the printer spooler itself make sure thier isnt any jobs stuck in the spooler, if there is delete them and also reset the printer spooler, if that doesnt clear them out reset the computer, this will help it, finally when you have that done, do a test page by going into the printer and faxes and right clicking the laserjet 1020 going into properties, and in the general tap click on the test page this should print out a test page. if it does then your printer is up and running.

It was the teflon sheet problem just change it
it costs around 6$

Thank u
Take care
bye

It seems like the problem is not the printer, but your Excel file.
