ENX Magazine November 2009 Article

A while back, we dove into the C123 style machines with a pair of articles that concentrated first on the Status Code meanings and second on the Diagnostics including NVM (Memory) codes & adjustments. The next piece of the puzzle is to have the Component Control Codes in hand. These tests can be run from the Control Console as long as you know which codes activate which parts.

This would also be a good moment to mention the newcomers to the series: the WorkCentre 5222, 5225, & 5230, which are extremely similar to the C123’s. There are some changes to supply item part numbers, but for the most part diagnostic procedures are most likely going to prove to be the same.

Let’s start with a quick refresher on how to get into the Diagnostic Mode. You’ll press and hold down the ‘0’ button for at least 5 seconds and then press ‘Start’ while you’re still holding down the ‘0’. This brings up a prompt for a Password. Enter ‘6789’ and press ‘Confirm’. The screen will reverse colors to show you that you’re in UI Diagnostic Mode. Now you’ll press the ‘Log in / Log out’ button. Select ‘Systems Settings’, followed by ‘Common Settings’, and then ‘Maintenance / Diagnostics’.

Now, from the Maintenance / Diagnostics screen you have a few choices. To test various parts, choose ‘Component Control’. Then enter the ‘Chain-link Code’ and press ‘Start’. Below is roughly what the screen looks like:

For some reason, the Service Manual’s list shows duplicate codes for the same component in a few cases. The Main Drive Motor is a good example. The list shows all of the following codes are for the Main Motor: 042-001, 047-006, 071-036, & 091-006. Personally, I had to see it to believe it. Taking the list to a machine proved that all of the codes were in fact valid. Similarly, the Registration Clutch has multiple codes for testing it as well. Why they did this is a mystery which is not explained in the Service Manual (at least I couldn’t figure it out). For the purposes of this article, the duplicates are dropped off the list. In addition, there are over 50 codes relating to the Finisher and Horizontal Transport (H-Transport) that have also been left off the list.

When you choose an ‘Input Component Code’ (for testing sensors & switches), each time you actuate or deactuate the switch or sensor, the counter will increase by one step and the read-out will change between “H” (high) and “L” (low). Below is a list of the ‘Chain-Link’ Codes for the Input Components:

I’ll continue with the OUTPUT codes next month. Happy troubleshooting to you all!
