Hardware Changes - Fuser
The C73x/X73x Fusers had a screw on the Duplex Guide
which made it difficult for customers to access accordion jams.
The C74x/X74x fusers do not have this screw so the guide can
be opened for easy access into the fuser.
To open the guide, simply move the release lever and unlock
the guide pin
C73x/X73x Screw
C74x/X74x No Screw
These new fusers are compatible with the C73x and X73x
printers. In time, only the new fusers will be available as a
replacement part for the C73x/X73x.
If this pin is not in its
“Locked” position, the
Fuser will not install.

Hardware Changes – Cartridge Contacts
To eliminate problems with errors associated with the cartridge contacts, the old copper colored
contacts in the C73x/X73x machine and Toner Cartridges are replaced with plated silver ones. In
addition, the printer contacts can now be ordered as replaceable FRUs.

Hardware Changes – MPF Pick Assembly
The MPF Pick arm is redesigned on the C74x/X74x to be more durable and to allow for easy removal.
Now, to remove the MPF Pick Arm, squeeze the green release lever and slide it off the shaft.

Hardware Changes – MPF Empty Sensor
To improve the MPF, a paper empty sensor now detects when the MPF is empty. An actuator inside the
opening of the tray springs upward when the tray is empty.

Hardware Changes – Scanner Lamp
Although the scanner looks identical to the X73x, the lamp light source uses an LED instead of a Xenon
lamp in the X74x models.
The procedure for servicing the scanner is the same if the CCD should need replacement.

Hardware Changes – C74x Power Consumption
The C74x has improvements for reduced power consumption. The power consumption levels listed in
the table below represent time-averaged measurements. Instantaneous power draws may be
substantially higher than the average. Values are subject to change. See www.lexmark.com for current
values.
Power Consumption by Mode:

Note: Some modes do not apply to every model. The power consumption levels listed in the table represent timeaveraged measurements. Instantaneous power draws may be substantially higher than the average. Values are subject
to change. See www.lexmark.com for current values.

Hardware Changes – Power Consumption con’t
Sleep Mode
The printers are designed with an energy-saving mode called Sleep Mode. Sleep Mode saves energy
by lowering power consumption during extended periods of inactivity and automatically engages after a
specified period of time. Factory default Sleep Mode Timeout = 30 minutes
By using the configuration menus, the Sleep Mode Timeout can be modified between 1 minute and 240
minutes.
• Setting the Sleep Mode Timeout to a low value reduces energy consumption, but may increase
the response time of the product.
• Setting the Sleep Mode Timeout to a high value maintains a fast response, but uses more
energy.
Hibernate Mode
Hibernate is an ultra-low power operating mode. When operating in Hibernate mode, the printer is
essentially off, and all other systems and devices are powered down safely. The printer will not
respond to faxes, print jobs or other cues that would normally “wake” the printer when in sleep mode.
By default, Hibernate Mode is not enabled. You can enable through the embedded web server or
operator panel menus: Settings > General Settings > Sleep Button Settings

Code Changes
The C74x/X74x uses a different firmware code than it’s predecessor, the C73x/X73x. The menus are
slightly different as well as some error codes. Lexmark is transitioning all laser printers to a
standardized error code scheme to make error reporting more consistent throughout all products.
If you have previous experience on the C73x/X73x, keep in mind that the error codes may not mean
the same thing on the C74x/X74x. In addition, if you need to update code on a 73x or 74x printer,
make sure you use the correct code as the 73x code is not compatible with the 74x and vice versa.
