HP 3055 Prints a line down the page

[CarlosP]

I am having some trouble with an HP Laserjet 3055, when I print a page while the printer is 'cold' , a small strip 1/8" thick of garbage prints down the entire length of the page..  If I print more than one page the error gets smaller and smaller and around the 4th page the printer prints perfectly...

If I wait over a minute before printing another page the 'line' resurfaces.

I've tried different toner cartridges and have done the printers cleaning command, nothing has helped...   Does anyone have any idea ?

Am I the only one with this problem ?

What does the "garbage" look like is it spotty toner all about and is there some on the back side of the page as well...or it it random letters and half characters?

If it is just spotty then you toner may be leaking try another toner and see if that resolves the issue, if it is random characters then is may be that the fuser is retaining some excess on it and that generally requires repair to replace but I suspect that the toner is the issue.

Is it a genuine HP toner if not they are prone to leaking the 3rd party type that is.

I have similar problem with HP LaserJet 2430.

While printing, characters from each line are repeated at 3 inch intervals along the length of the paper at about 2 inches and 7 inches from the left margin that appear as two grey bands on the printout. The widths of the bands are approximately 2 characters and 8 characters. For example when a single line is printed the characters at 2 in and 7 in locations from the left margin repeat at 3, 6 and 9 inches down from the printed line and the intensity of the printing decreases.

For example if I print a printer test page, the HP logo at the top right corner will repeat with reducing intensity at 3, 6, and 9 inches from the first logo print.

Similarly if I print a word document with just one line of numbers 1234567890 repeated for the width, the numbers 23 at 2 inch and 67890123 at 7 inch from left margin will repeat every 3 inch along the length of paper (portrait mode) with decreasing intensity.

While printing documents with multiple lines this causes two grey vertical bands along the length of the paper.
