LASER, INKJET, DMP PRINTER TROUBLESHOOTING

Laser, Inkjet, DMP Printer Troubleshooting

HP's Inkjets printers do not work when the top cover is open, there is a switch on / off through the top cover, only when it is closed, the switch inside the printer is turned on and Cartridge is Pork in its Parking Place.  This switch and paper sensor are connected to a small circuit, this circuit is located just below the top cover, due to its settings, the printer stops working and the cartridge is not parked. 

The specialty of HP DeskJet’s is its cartridge parking, under this, when the top cover is opened, the cartridge unit comes in the middle and halts, so we can remove or replace the cartridge.  When the Top Cover is closed, the Cartridge unit itself goes to its parking place, not doing so means an error in the Printer like Cartridge malfunction, Cartridge not working properly, Cartridge circuit not having proper cable connection.  To be, Paper sensor circuit on Misaligned etc. 

The Paper Feed LED blinks when the Top cover is open or this LED blinks even if the cartridge is damaged, or absent, or the cartridge is not sensed, the paper is out. 

Some common errors encountered in HP DeskJet:

·         Paper out message is received while the printer is feeding paper.  Paper feed LED is blinking. 

·         Check the printer's paper sensor circuit There is a plastic lever between the paper sensors that is attached to the printer's Roller Cover.  This is a complete Alignment Miss, Align it.

· A switch in the paper sensor circuit should be turned on by closing the top cover.  Check whether it is turning on or not.  This problem can come even if the printer's cabinet is not installed properly. 

· Due to the drying of ink on the track of the circuit in the cartridge, the connection between the cartridge and the printer cannot be made, clean the track of the cartridge.

The printer makes a lot of noise while printing and the print head unit sometimes gets stuck on the side of the edge.

·  Printer needs servicing.
