How do I replace my HP Color LaserJet 4700 Image Transfer Kit? I don't have the manual for it.


Replace the ETB when a REPLACE TRANSFER KIT message displays on the control panel.
1. Turn the printer off.
2. Open the top and front cover.
3. Lower the ETB by pulling the green handle at the top of the unit downward.
4. Press the small blue latches located on either side of the bottom of the ETB and lift the unit out
of the printer.
5. Install the new ETB.
6. Close the front and top covers.

HP Color LaserJet 3500, 3550, and 3700 Series Printers - 59.99.00 Error Displayed on the Control Panel Issue

When faced with a 59.99 error, we have found additional ways to solve the issue since the service manual was written.
Error: 59.99.00 Description: An error occurred in the secondary transfer engaging mechanism. Solution

Follow the troubleshooting steps below:

  1. Fuser seated improperly. Reseat the fuser.
    NOTE: You may hear grinding sounds from the right, rear of the printer associated with this specific failure also.

  2. Faulty secondary transfer engagement sensor. Replace the secondary transfer engagement sensor. (PS16, part of paper pickup/feed assembly)

  3. Faulty secondary transfer engaging solenoid. Replace the secondary transfer engaging solenoid. (SL4, part of paper pickup/feed assembly)

  4. Faulty feed motor. Replace the feed motor. (M1)

  5. Faulty DC controller PCB. Replace the DC controller PCB.

  6. If the 59.99 error only occurred after removing and reinstalling the paper pickup/feed assembly, what may have happened is that the secondary transfer engaging solenoid SL4 may have become dislocated. See figure below. Verify position of tab on top of solenoid.

My 4700dn is giving me the replace transfer kit message. I have swapped out known good transfer kits and the printer prints fine but I still get the replace transfer kit message. What can I try next?


The message only clears when you install a new transfer unit, one that hasn't been used before. If you want to clear the message, you'll have to install a brand new transfer belt.
If you know the service PIN for the 4700, you can probably go into the service menu and clear the message, but otherwise a new transfer unit is the only way to go.

I have a HP color laserjet 4650dn that when you print a document, there are pink spots all throughout the document. Is this due to replacing the fuser or transfer bar? There are no warning indications on...


It depends on the true color of the spots. If what you describe as pink are actually Magenta colored spots then I would suspect the Magenta toner/drum cartridge. It is definately not the fuser. The transfer bar or actually transfer belt unit in this case is doubtful to be the cause. A defect in the tranfer belt unit does not normally show up as 1 color. It is usally multiple colors. I would open the front cover and at least visually inspect the Magenta toner cartridge. If you have a spare unit, even an old one to swap it out with even better. Look at the color of the Magenta toner and compare it to the spots you are seeing. If they are similar then in my opinion the problem is in the Magenta drum unit.

Transfer kit


The transfer kit is unrelated to the toner. On most printers it gives you the message that it needs replaced after X number of prints. Depending on page coverage and the quality of the paper you are using there may still be some life in it and you can clear the message and print until the image quality is affected then change it.

59.0A error in hp color laserjet 3700


All 59.XX error codes have to do with a motor failure of some type. I don't know anything specific about 59.0A but 59.A0 means that either the drum motor failed to start or something bad happened while it was rotating. If you feel like tackling it yourself you can try reseating all the connections to the drum motor and the DC controller board. Other possibilities could be a bad drum motor or a bad DC controller. HP says you can also get this message when the tranfer unit is missing or improperly installed.

If you don't feel like tackling it yourself then it's off to a repair shop unless it's under warranty, in that case call HP.
