firstly check whether the problem is internal or external-
Have the printer print out the config page- if you can see the image then the issue is external to the printer- check your PC settings
If you cant see an image-
You say you have allready changed the toner unit, was this before the fault or after?
under where the drum/toner cartridge sits there should be a Black 'transfer' roller that will line up with the drum surface when inserted- if this is missing or failed then the image cannot be ' transferred' from the drum to the paper. this is just one possibility, if your not sure wheher the transfer roller is working - stop a print half way through- remove the paper and toner unit - slide the drum surface protector to the side and look at the drum surface for a latent reversed image in toner on the surface of the drum, if you can see an image the problem lies with the transfer element, if you cant see an image then it could possibly be the charge chorona/ HVT PWB / Laser unit, main Pca, power supply hope this helps

I have an HP 4515 that is printing blank pages. I have tried to replace the toner and the power supply board. Neither resolved the issue. When the paper gets deliver out the paper is warm. This occurs when...


I believe I understand your issue:-
The printer is able to come to ready- your still able to navigate the menus. the printer goes through all the motions of printing except producing an image-
Having the machine print a test page ( internal Print ) tests whether the formatter is still able to generate a digital image ready for the print engine, but does not diagnose the print engine-
1) power down and remove power cord
2)remove the toner cartridge, use a pair of pliers and gently rotate the drum ( within the toner cartridge, a drive gear/mesh can be found on the end of the toner unit)- are you able to turn this drum or has it seized?
if it doesnt replace the new toner with another NEW toner and try again
3) return the power and power up the machine having first disconnected all network connections.
allow the machine to come to ready.
4) ask the printer for a config page ( internal print) and estimate when the paper is immediately below the drum surface ( toner cart) and using the power switch turn the printer off- causing a jam in the centre of the printer - this is ok we do this to see if an image has been generated on the drum surface- remove the toner cartridge and slide the drum protector plate to the side, look carefully at the drum suface ( you should see a latent image of a config page, at this point look at the paper still jammed inside the printer and see if there are any signs of toner ( there should be part of an image allready on the surface ) now if there is an image on the drum but no image on the paper then I would replace the transfer roller and or transfer HVT power unit, if however there is no image on the drum then you have a very serious problem which will require a new laser unit ( but this should really come up with a diagnostic error code)or Primary HVT unit.

064 code


Symptom

E064 is indicated on the control panel. The error description is: The presence of a high voltage error is communicated by the composite power supply. The output for primary charging, developing, or transfer has deviated from a specific level of voltage.

Cause
* Adjustments in Service Mode are Incorrect
* Transport Assembly is Not Engaging Properly
* Dirty HVT Contacts for Developing Assembly and Charging Rollers
* A Paper Clip on HVT Contacts or Developing Assembly
* Faulty Transfer Roller
* Faulty Static Charge Eliminator
* Defective Composite Power Supply
* Defective DC Controller PCB Assembly

Action

1. Check the values in Service Mode and make sure they correspond to the Service
Label. If the copier receives a spike or surge through the 240V line these values can change (can also give you blank copies). Take particular note of the Dev Bias
setting. [COPIER > ADJUST > DEVELOP > DE-DC]
2. Make sure the Transport Assembly is engaging properly. The Transfer Roller should
make good contact with the drum. Check condition of screw (XB6-7501-007) and
Pressure Plates (FB5-4816-000 & FB5-4817-000) for the Transport Assembly.
3. Clean HVT contacts for Primary/ Transfer Charging Rollers and Developing
Assembly. Inspect for any paper clips.
4. Replace the Transfer Roller (FF6-0104-000).
5. Replace the Static Charge Eliminator (FF5-7246-000).
6. Replace Composite Power Supply followed by DC Controller PCB Assembly

DP-190 Blank Copies


By the write unit i guess you mean the LSU. If you've already ruled out the the image drum and transfer roller you're only left with a few possibilities. I'm also guessing this fault only happened after you replaced the LSU??

1 is there something obstructing the beam from the scanner to the image drum.
2 have you damaged one of the 2 harnesses going into the LSU (check the contiuity) also check the connections on the system board.
3 The high voltage power supply may be faulty.
4 The system board may be faulty.

I repair lots of the DP180's the european version
