Error Codes 66.0015 & 79.00FE Laserjet 8100 DN

We have put in new cables,tried a new formator but still are getting these errors. The printer will work fine without the 5bin mailbox. Do we now replace the mailbox? Will this definitely work? I don't want to spend more money and not have a solution. We have had a service rep here 4 times now. He says mailbox but he swore the formator would fix it.

According to the information I have the error is usually caused by the pca board of the external device and in your case the 5 bin mailbox. If you provide the part number of the mailbox (usually begins with a C) and I can find the part number I will provide it to you.

Just did some research and your unit should be a C4787A and if it is the pc board is C4785-60543. The problem is the board is over 700.00. Found the link below which has it for 654.00.

Here is a place selling the part for less then 100.00. Wonder if it is good.

After looking at the service manual I see that the DC Controller is a part of the formatter assembly. If the rep tried a new formatter would that not rule out the DC Controller?

You are not looking in the right place or misreading the manual. The error only can only be caused by 3 items. The formatter which does not contain the dc controller besides the dc contoller will not cause your error. The c link cable and the pca board. The manual recommends the pca board first and that board is the control board contained inside the 5 bin mailbox unit and not the printer.

The new part arrived today. We are still getting both error messages! I tried a cold reset. 66 twice and the 79 once. Any suggestions?

Since the error messages we have not had any additional problems the mailbox seems to be working fine. Thank you for your generous assistance.
