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.

Good Luck.

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?

[DavidZuts]

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.

Okay, found it. Thanks for your help and for finding the part. I will let you know how it works out.

I wanted to post an update. We are waiting for the part. I found it for 292.00 at Impact computers and electronics.

[Toni Shar]

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?

[Toni Shar]

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