Turn the printer off and disconnect

Fuser Lamp

the fuser lamp wires from the fuser.

Lamp Cable

Check for continuity across the fuser

Thermistor

lamp wire contacts. If there is

LVPS

continuity, go to step 1: Continuity.

 

If there is no continuity, go to

 

step 2: No Continuity.

 

Step 1: Continuity

 

Measure the voltage at connector

 

CN202 on the LVPS. It should match

 

the line voltage. If it does not,

 

replace the LVPS. If line voltage is

 

present, check the fuser lamp cable

 

for continuity. Replace if

 

defective.Make sure the fuser

 

thermistor is correctly connected to

 

CN1 on the LVPS. If the problem

 

persists, disconnect the thermistor

 

cable from CN1 on the LVPS board

 

and measure the voltage between

 

CN1-1 and ground. The voltage

 

measures approximately 3.9 V dc. If

 

the voltage is incorrect, replace the

 

LVPS. If correct, replace the

 

thermistor.

 

Step 2: No Continuity

 

Check the thermal fuse for continuity.

 

If incorrect, replace the thermal fuse.

 

If correct, replace the lamp.

With a print speed of up to 30 pages per minute (ppm) and a first page out time as fast as 6.5 seconds, users can expect quick document handling. The E310 supports a maximum print resolution of 1200 x 1200 dpi, ensuring sharp text and crisp graphics on printed materials.

One of the standout features of the E310 is its energy efficiency, designed to consume less power during operation, which can lead to significant cost savings over time. Additionally, this printer supports duplex printing, allowing for automatic double-sided printing, which not only enhances productivity but also helps to reduce paper costs. With a monthly duty cycle of up to 30,000 pages, the E310 is well-suited for medium-volume printing tasks.

On the other hand, the Lexmark E4044-XXX is designed for more demanding office environments needing higher output and advanced features. This monochrome printer also emphasizes speed and efficiency, with print rates reaching up to 40 ppm and a first-page print time of about 6 seconds. The E4044-XXX enhances productivity further with its duplex printing capabilities, and it can accommodate larger paper formats with options for various media types.

With a maximum print resolution of 1200 x 1200 dpi, the E4044-XXX provides even more precise text and graphics compared to its E310 counterpart. An impressive monthly duty cycle of 75,000 pages makes this printer suitable for high-volume printing needs. The model also supports fleet management capabilities, allowing businesses to manage multiple devices effectively through Lexmark's software solutions.
