SOURCE: HP LaserJet P3005 printer prints wrinkled paper

2 reasons:
1. Was there a paper jam prior to this problem? It could be that the paper was pulled out and a small bit of it is stuck on the pins that guide the paper from the heat roller. If no torn jammed paper prior to this issue, then check out 2.

2. the heater/roller is damaged and needs to be replaced. I would suggest you take it to your nearest HP dealer to properly diagnose this for you.This would save you unnecessary cost in trying to pull it apart and causing more damage to it.

Good Luck,

SOURCE: HP laserjet 5550 not printing cycan. Replaced

You will not find the answer to this problem on any forum as I have searched each one! However I have had the same problem and found out that if you have reseantly replaced or reseated the Paper Pic-up assy you may have not pushed down the plastic top cover which sits directly underneath the Cyan Cartridge, this will cause your 5550/5500 to think there is no problem and carry on printing without any error messages.
I'm just a man doing a boys job, lol

Hello, this error related to the additional memory installed into the printer. It could be just the memory or the Formatter board itself. The memory can can be removed quite simply.
1) Turn the power off to the printer.
2) Slide the right side cover off, moving it towards the back.
3) Remove the memory DIMM from the formatter board.
4) Turn the power to the printer back on.

Does the printer come "READY"? If yes, then the memory is bad, If NO then the formatter is bad and will need to be replaced.

A good source for part

When i on the printer then "standard top bin full pls remove paper" shows massage. I have HP laserjet printer 3005 dn . so how can i solve this problem.

You have a broken sensor flag most likely or a defective sensor. Sensor and flag located under the top cover in the top right hand back corner. Also check to see if the cable is connected on the sensor and DC controller. If everything is ok, mostly likely defective DC controller.
Often I do repairs on printers because the customer does not use it properly or just plain abuses it. Just read the manual before using.

Hp4345 51.10 error i have replaced the laser unit, dc controler board, engin power supply and the pfc power supply, the 2 cables from the llaser to the dc controler

It's still a laser beam detect error, you need to make sure the safety shutter is opening when the door is closed. It blocks the beam from your eyes and also the beam detect sensor. If all is good, you could have gotten a defective laser.

51.20 error message on HP laserjet 4250n printer

It is an error with the laser scanner unit
1 Press ( SELECT button) to continue.
2 Turn the printer off and then on.
3 Reseat the connectors between the
laser/scanner and dc controller
PCA (J83 and J84).
4 Replace the laser/scanner assembly.
See Laser/scanner assembly.
5 Replace the dc controller PCA. See
Dc controller PCA.

If nothing from above works and the printer is no longer in warranty, it is possible if the printer is being used in a very dirty or dusty enviornment that the lens and optics of the laser/scanner are so full of debris that the beam detect error occurs. You can remove the top cover and the big black box in the center is the laser scanner assembly. Remove the screws securing the top cover of the laser scanner and remove and clean up all the optics to include the main mirror in the front. I usually use a damp q tip and for the mirror I slide up from toner cartrdige shutter area and observe from the top as it cleans the mirror. Removing the complete assembly on this model is not easy since there are a couple of cables going to the dc controller which are difficult to remove so removing the top of the assembly is easier.

HP LaserJet 5200tn printer that doesn't print dark enough.

If that's okay, then these are the other possible causes:
Transfer roller is defective or incorrectly installed. If the
transfer roller loses conductivity, it cannot effectively pull toner from
the drum to the paper.Transfer roller is defective or incorrectly installed. If the transfer roller loses conductivity, it cannot
effectively pull toner from the drum to the paper.

Action 5

Inspect the transfer roller for correct installation and contact. If the transfer roller is damaged, replace it.

High-voltage connector springs are dirty or defective.

Action 6

The high-voltage connectors are mounted on and above the dc controller and protrude into the toner cartridge cavity. Check the springs for functionality. Clean if dirty, replace if defective or missing.

Laser/scanner door is not opening correctly.

Action 7

1. Remove and reseat the toner cartridge.

2. Check the laser/scanner shutter door for proper operation. If it is defective, replace the laser/scanner assembly.

The dc controller is defective. The dc controller contains the high-voltage circuitry.

Action 8

Replace the dc controller.
