Lexmark MS810 series Maintenance Kits and Fusers.
The Lemark MS810 family of printers include the MS810 itself, the MS811 and MS812 which are faster, the MX710 and MX711 which are multifunction printers and the MX810, MX811 and MX812 which are digital copier style machines. The MS710 and MS711 are aimed and manufacturing and retail labelling.
When any of the Lexmark MS81x series printers Display "80 Sheduled Maintenance" the maintenance kit needs to be replaced. After a grace period during which it gives further warnings the printer will stop working showing "80.3x" until the kit is replaced.
Maintenance kits are considered "customer replaceable units" (CRU) in the same way as imaging units. They may be slightly less easy because the job is done less often; and the job can be combined with general maintenance on the printer so sometimes an IT department will do it.
In the past Lexmark made 3 maintenance kits and fusers available, matching the mains power in the region (100, 120 or 200 Volts). With these new printers there are about 19 possible maintenance kits because there are:
- belt fusers giving fast economical performance
- two different versions of the belt fuser depending if you primarily use A4 or US letter paper
- hot-roll fusers for labelling
- and "returns" fusers for recycling by Lexmark
Why You Need Maintenance Kits
Printers innevitably use toner powder in the print process. The Lexmark MS810 engine printers take toner cartridges witth 6,000, 25,000 and 45,000 page lives.
The photoconductive drum in the imaging unit wears out through contact with the paper or light exposure. So do the various rollers; all are replaced with a new imaging unit. The imaging unit in these printers expires after 100,000 pages
Paper pickup rollers generally have a long life, often exceeding two hundred thousand pages in big professional printers like this. Roller life does depend on the print media. When rollers are exhausted they will usually have no surface texture and the printer will frequently fail to move paper out of the tray or if the separation pad or roller has worn it will move two or more sheets. Rather than use electronics or software to guess when the rollers are failing it is usually left to user observation.
Fusers wear out as well. The non stick properties of the hot surface decline, so it gets flecked by old toner and starts to mark the page. Lexmark have generally used a belt instead of a roller in these printers. The belt allows a very rapid first page out time of around four seconds and as a side effect reduces the printer's energy consumption. Ultimately the belt will begin to split, usually where the paper edges make frequent contact - the problem is sometimes called "edgewear". Lexmark have tried to engineer edgewear out by making fusers specifically for the paper size. Fusers occasionally fail due to the constant hot and cold cycling of their heater element and even because of power surges.
There can be 6 types of fuser that might fit in any region. Luckily only one of them is likely to be very common. In the US that is the Type "00" and in the UK the Type "01".
It is wise to check which type of fuser you have before ordering. That can be done through the front or back of the machine, or through the built in Embedded Web Server.
How to identify the fuser:
Identifying the type of fuser used in the printer from the front of the machine:
- Open the front cover.
- Remove the cartridge and imaging unit.
- On the EP frame, see the number in the area.
From the rear of the machine:
- Remove the rear upper cover.
- Pull down the redrive.
- See the number in the area.
The Embedded Web Server (EWS) also gives the fuser type
- Under the Reports button on the left Select Device Information
- About 14 items down the list is the fuser type.
MS810 Series
The Lexmark MS810, MS811 and MS812 printers all use pretty much the same hardware apart from the case parts and control panels. The model numbers reflect different print speeds set in firmware. Fuser and pickup rollers are the same.
MX710 and MX711 are multifunction printers - ie styled like a printer with a scanner on top. These machines use the same fuser as the printers.
MX180, MX811 & MX812 are styled as digital copiers; they use one of the same set of fusers.
MS710 & MS711 Difference
The MS710 and MS711 printers are special purpose machines using the same broad hardware but a different hot roll type fuser appropriate to price tickets, barcodes, garden center labels on vinyl and other manufacturing types of task. They naturally take a different maintenance kit.

License Type: If the fuser has a Return license type that means the customer is under licensed agreement to return the fuser once it is replaced. If the customer does not wish to accept this license agreement, unlicensed fusers are available. You may need to contact Lexmark to change your license type
Note: The MS71x models have a Hot Roll Fuser similar to previous generations of workgroup mono products. The fuser motor and other components also differ so the fuser type cannot be changed.
Note: The MS81x, MX71x and MX81x models have a Belt Fuser Only.
Shipping and Storing Fusers
Fusers incorporate a pressure roller which pushes up against the heater. Considerable pressure is used. The pressure roller may be distorted if it is left static under pressure for a long time. Characteristic of this problem is that a badly stored fuser makes a "whump-whump" noise when it is used and the intentation in the pressure roller can be felt if the fuser is turned by hand. If the damage is minor the roller may recover after some use but meantime there could be slight damage to prints and the load on the motor is not good for the printer.
Belt Fuser (MS810, MX710, MX810 Series)
Before shipping or storing, press the sleep button and wait until the control panel turns OFF before powering down. This will allow time for the belt fuser nip mechanism to open. Belt fuser CRUs are shipped with the nip open.
Hot Roll Fuser (MS710 Series)
After the device is turned OFF, lift the upper door, remove the cartridge and imaging unit then slide the fuser saver (‘wedge’) into the fuser nip per the included instructions.
Hot roll fuser CRUs are shipped with rear wedges that open the nip to prevents a flat spot on the fuser rolls from sitting for a period of time. The wedge needs to be removed before installing.
Service Maintenance
The Service Manual gives the following recommendations on service calls. The maintenance components are changed at 200,000 page intervals so that is good time to carry out the inspection and cleaning suggested.
So whilst the fuser and maintenance kit are Customer Replaceable Units the inspection and cleaning involved might go beyond normal user actions,

Cleaning
Although Lexmark has several patented mechanisms to stop toners and imaging units leaking laser printers do commonly build up some toner contamination. The trouble is usually minor if only manufacturers original catridges are used, some remanufactured cartridges can create a serious mess. There are hints on how to clean printers here .
