Firmware versions and their effect on ICE/IDM

Firmware, to take a very simplified view is similar to an Operating System for your printer or MFD.  

The firmware can control or have an effect on many facets of the operation of a device, but for our purposes, we're largely concerned with the MIB.

The MIB is, again very simplistically, a database of counters and supplies and supplies levels maintained by the device.  The MIB is what ICE interrogates to obtain counters and supply levels, and in turn, uploads that data to IDM where you can generate reports and set alerts.

So changes to the firmware can drastically effect the performance of ICE and IDM. 

Manufacturers of printers and MFDs will very often release periodic firmware updates for their devices.  These firmware updates have the ability to address issues with devices, and they have the ability to expose new counters or supplies that previous versions of the firmware may not.

What all of this means in terms of ICE and IDM, in practical terms, is that when you encounter a count discrepancy or an issue with supplies reporting, and that issue or discrepancy is not consistent across all instances of a model, then that is a clear indication that you should be looking at the firmware versions on the devices.

For example, if you have two devices of the same model, and one is reporting more meters than the other, check firmware. If you have two devices and one reports 5% toner for all toners every two weeks, and the other consistently reports it's toner, check firmware.

Whenever two outwardly identical devices exhibit very different results when being scanned by ICE, the first thing to check is firmware.

For information about what a given firmware release addresses or implements, please contact the device manufacturer.
