Lexmark MS31x/41x/510/610 & MX310/410/51x/61x Product Study Guide

Hardware Changes

The new MS and MX series printers have significant hardware and functionality changes from previous
models. Below is an overview of these changes.

Cartridge Shutter/Plunger

The Toner Cartridge has a built-in shutter that closes when the Access Cover is opened.
The Cartridge shutter is opened by the Access Cover Plunger when the Access Cover is closed.
The printer is shipped from the factory with the Access Cover Plunger in the downward position.
Development recommends removing the cartridge and imaging unit for normal ship and storage
needs.
For cases when supplies need to remain in machine, leave the plunger engaged. Testing has shown
that shipping or moving these models with all or some of the supplies does not cause any significant
leaks. The port and seal designs are very robust.
If the plunger is put into the 'ship' position without proper packaging, there is HIGH RISK that a
user may simply turn on the printer and start printing – resulting in a 31.46 or 31.66 replenishing
error or potential damage to the cartridge.
The most robust process is to put the plunger into the 'ship' state, but you MUST repackage the imaging
unit (and cover the input sensor) to ensure that the front door is opened the next time the printer is turned
on.
