Fixing a Paper Jam - HP LaserJet 1020 Printer

can you please help me to reset may old model selex GR-1020

Hi,
Clean the Paper Feed Rollers with wet cloth.Then go to start-ControlPanel-Printers-select Hp1020 printer-properties-features-change the Paper Type as PLAIN PAPER.

when i installed phaser 3110 mfp
my foxpro working directory changed to monotone imagine inc

pull out the paper drawer and look on the ceiling of the compartment. you will see a little orange rubber roller that should be clicked inplace. it feeds the paper up into the roller. also, the drawer itself contains two sensors. if you go to the xerox page you can download the pdf that lists all the parts and the errors and how to disassemble the whole thing. i have the same printer and got a print head error and a paper jam that required complete disassembly. feel free to email me for additional help.

Hello sir;Track back the paper you pull through you will find a senser either stuck or come off, put it back property.

three lights are for paper jam, replace toner cartridge and replace dru, cartridge. If there is zigzag line it is paper jam if there are six small dots it is for toner cartridge and if it is one circle it is for copy cartdisge. You can contact me for mfurther support at [email protected]

This machine problem can be very involved.
A paper jam as described can be in any locations of the copier.
First of all when the toner-developer falls on the base of the paper feeder, it can contanimate all paper feed shafts and even sensors, and plug connections.
Worn feed rolls can cause the machine to jam. Clean the rollers and see if it corrects the problem.
A bent paper tray can cause the copy to skew, causing jams.
Sometimes the plasic paper path baffles are warped leaving narrow gaps in the paper feed path not allowing the paper to go through properly.
A bad paper feed sensor can cause inttermittant paper feed jams. This sensor is located just above the feed rolls. A involved process to take out without breaking the plastic components.
The machine has paper feed clutches located at the back of the feed rolls. To get to them it is also involved. Sometimes these clutches slip and will cause paper feed problems. There paper feed solinoids may operate intermittantly not allowing the paper feed clutch to operate correctly.
The main board can also cause these types of problems, not allowing the correct signal to operate the paper feed solinoids.
There is so much in this area to locate and isolate for paper feed problems.
If all else fails, call Xerox for a service repair.
