Work Center 123/128 Technical Info: Part 1

 

 

 

Introducing: Xerox C123 style… Introduction & Status Code Meanings for the Xerox CopyCentre C123, C128, & WorkCentre M123, M128, Pro123, Pro128.

 

The model numbers which are in the C123 style include: CopyCentre C123, C128, 133, WorkCentre M123, M128, M133, Pro123, Pro128, and Pro133. I should mention that the 133 models are not mentioned in the 2004 release of the Service Manual which was used as the primary reference material for this article (available on Xerox’s Documentation Website www.xdss.com under part number 701P26490 for $388.87). Considering that they are a newer release which shares the same supply part numbers, it stands to reason that most of what is in this article will apply to the 133’s

The C123 style machines are being welcomed with more warmth than the C118’s before them. Several technicians who are selling and servicing them reported them as being excellent machines. The opposite was said of the C118 machines. These new-comers, I am told, are workhorses which give very little in the way of problems. They are also rather technician friendly. The two types of machine share a similar appearance. They actually use the same part number for the drum cartridges… but that is where the similarities pretty much dry up. The Status Codes and Diagnostic Codes of the C123 are completely alien to the ones for the C118. Feed components are similar in some of the trays, but the Document Feeder parts are nothing alike. The Toner Cartridges look similar although the C123 is considerably larger and uses a different CRUM (Customer Replaceable Unit Monitors… the chips which track the count and identify the version of the cartridge). The same is true of the newest ones… the WC-5225 style. The C123 series machines are selling heavily out there…. So they’ll be showing up in greater numbers than the C118’s.

There is also a Phaser printer which is related to the C123. The Phaser 5500 is the same basic engine, with the main difference being that there is a simpler User Interface (no touchscreen) and no Scanner up top. Naturally with the different User Interface, the diagnostics will be quite different as well.

The Supplies for the C123 style are very close to the C118. The Drum Cartridge is actually identical right down to the part number (13R589). It has a yield of 60K and sells for $199.-. The Phaser 5500 version of the Drum Cartridge (113R670) will be different (probably just the CRUM will be different). The Toner Cartridge (6R1184) are physically different between the C118 (6R1179), & C123 (6R1184). The Phaser 5500 (113R668) & Phaser 5550 & the WC-5222/5225/5230 all have the same cartridge as the C123 but the CCRUM is unique on each so you can’t freely interchange them. The CRUMS (Customer Replaceable Unit Monitors) used on both the Drum and Toner Cartridges on these machines are RF (Radio Frequency) types of chips… They never makes any physical electrical connection whatsoever. Instead the machine uses radio waves of some sort to read and write to the CRUM’s chip.

The Developer station (yep, it’s dual component, so it actually does have developer material) is spared as part of the Drum Cartridge. They call the Drum Cartridge the “Xero/Developer Cartridge” at times in the Service Manual. The Toner cartridges have a small bit of Developer material mixed into them so the material remains fresh in the machine throughout the life of the Drum Cartridge (Xero / Developer Ctg).

Now for the Status Codes. This list will have to be abbreviated somewhat because the Service Manual acknowledges over 600 Status Codes. The general meanings of all of the code prefixes will be represented as the first part of the code (the prefix), then a dash followed by “xxx” to represent the second half of the code (example 010-xxx). Those generalizations will be in bold text in the table to follow.

The book is littered with acronyms, and although there is a Glossary of Terms, many of the acronyms which I couldn’t guess the meaning to, are not listed. It was getting frustrating till my wife suggested that I Google the acronyms… actually found quite a few of them. Good thinking Joann!

As noted above, some of the fuser codes need to be reset from the diagnostic mode before the machine will attempt to warm up again. We’ll be getting into the diagnostics in the next article, but I think that you should at least know how to use the diagnostics to get the fuser codes to reset… Don’t want to leave you hanging!

Resetting Fuser Codes (010-320, & 010-327)

 

* Resetting Fuser Codes (010-320, & 010-327) : (reset NVM code 744-220 to ‘0’)
First enter UI (User Interface) Diagnostic Mode: Hold down the ‘0’ button for 5 seconds and then press the ‘Start’ button while still holding the ‘0’ button. The machine will prompt you for a Password. Enter the default Access Number: ‘6789’ and press “Confirm”. The colors on the display will be reversed to indicate that you are now in diagnostic mode. Next press the “Log In/Out” button on the Control Panel. Select ‘System Settings’, ‘Common’ Settings, followed by ‘Maintenance / Diagnostics’. Now you will find the main menu includes one choice called “NVM Read / Write” (NVM is Non Volatile Memory)… Now you can enter your “Chain-Link” code (in this case 744-220) and press ‘Confirm / Change’. The current value will appear (if the machine is in a fuser fault condition, the value will be set to “1”). Select the “New Value” column and input your new value (‘0’). Select “Save” and the new number should now appear in the “Current Value” column. You can turn the power off and back on at this point. The machine will attempt to warm up the fuser again. If the condition which caused the fault in the first place is still happening, the Status Code will return after a few minutes of attempting to warm up.
