All blank pages could either mean: On the scanner side: * Mechanical error, you'll need to perform service on it to reanimate it again. * You can check if it is on the scanner side by printing a test page on the printer. If it prints fine, the problem is in the scanning process.
On the printer side: * Dirty connectors between toner/drum unit and machine. Remove the toner/drum package and clean the metallic cylinders on the left and right side of the toner/drum unit, then reinsert package into machine. * Bad toner and/or drum unit. Replace should solve it. * Mechanical error, you'll need to perform service on it to reanimate it again. * You can check if it is on the printer side by either scanning to a connected PC or sending a fax to someone. If the scanned/faxed page looks fine on the pc/fax that receives the fax, the problem is in the printing process.

Hi there,

I believe there are 3 possible causes for this issue; toner drum, fuser or transfer roller - more than likely I would dismantle the printer and check for lines on the fuser. But just in case remove the toner and carefully release the flap to reveal the toner drum - if that is scored and the lines correspond to those on the print-out thats the cause.

Depending on the type and model of your printer this could be several things mostly related to the cartridge or drum if you have a separate toner/drum system.. Since you have stated you have shaken the toner, I am assuming you have a laser printer. New belt, has me confused. Green thing leads me to think you are talking about the drum. If so, did you purchase a new toner cartridge or new drum cartridge?

Several components inside the toner or drum cartridge will cause vertical streaks. It depends on where these streaks are occurring and how wide the streaks are. We call these repetitive defects and they can be measured to determine which part is at fault.

Also, if this is a multi-unit machine (print/copy/fax/scan) Check the platen glass or ADf feed unit for white out. That has been a major culprit of vertical streaks on the page.

More specifics about the model of machine and cartridges being used would be helpful in trying to solve this problem for you.

The HP2840 is a sigle sided scan device. To copy both sides you must copy one side then load the one sided copies in the tray again and repeat the process again. Pay close attention to which side is printed on and scanned on both the original and copies. Also the top to bottom feed order of the auto doc feeder and paper tray. It's easy to get them out of order and copy first page onto last or worse, both sides onto one side of the copy.

The HP2840 isn't capable of scanning both sides and printing both sides at once.

Hope that helps you. If so hit me with a FIXYA. If not hit my user name and further describe the problem to me so I can help you further.
