and it can be difficult to determine the exact cause. But the more you know about what the code means and what kinds of things can cause it, the better equipped you will be to troubleshoot it. Note: due to their similarity, we will refer to the 49 and 79 errors as a single error. Background on Firmware In the article Firmware Upgrades we discussed in detail what firmware is and what it does. See that article for full details, but in brief, the printer’s formatter board is a computer of sorts, and firmware is the program that tells the formatter board what to do and how to do it. It is permanently stored in ROM chips, either on the formatter board itself or on a SIMM or DIMM that plugs into the formatter. Firmware Addresses Both the 49 and 79 errors are firmware errors, and they are always accompanied by a 4-digit firmware address (for example, 49.4C02, or 79.01FE). The four characters after the decimal point are the firmware address at which the error occurred. In theory, this is important information – if you had access to the firmware source code, and were able to understand it, you could see exactly what the firmware was trying to do at that address, and that would help pinpoint the cause of the problem. However: (1) For any given printer, there are thousands of firmware addresses – far too many to list them all in a service manual; (2) Even if you could see the firmware source code, it would be unintelligible to you unless you are a software engineer; (3) The firmware is proprietary – HP does not want people to be able to see the source code. For these reasons, the 49 and 79 errors are listed in the manuals as 49.xxxx or 79.xxxx. For our purposes, the specific address is useless, and we must troubleshoot these errors on general principles. The 49/79 error is telling you that the normal operation of
