There are a couple of things to try. The first one will most likely resolve your problem.
Unplug the machine and go to the back. On the back cover, you will see another cover, about 4 inches x 4 inches. That cover is just held in with two plastic latches. Just flex them and remove that small cover. Inside there, you will see 2 memory sticks. Just move the white tabs outward and remove both memory sticks, just note which is the top and bottom stick, it does make a difference.
With the memory sticks removed, plug the machine back in and turn it on. Allow it to power up. Once the machine powers up, shut the machine down , insert the memory sticks, then power the machine back up. Your machine should return to normal operation.
The memory you removed is the difference between a M20 and an M20i.
Now, if that doesn't work, you may have a shorted heating element in fuser. To eliminate that issue, you have to open the right hand door, on the upper , ( I would say 2/3rds) of the rear side you will see a thin plastic cover with a white wire running under it. Remove that silver screw, pop the white connector out and try starting the machine with the fuser unplugged, you will most likely get a message that says " Open Heat Error" but it should not reset.
If that is the case and the fuser is bad, you will want to go onto google and look up ' the parts drop'. Call them and ask for Britt,he will have the part at a better price than Xerox. You can't just replace that heat roller, its a weird setup on the M20.
I dont work for the parts drop, but I have done business with them for years and they are the best in the business.
If both of those fail to resolve your problem let me know. Would be very odd if one of those 2 items doesn't recsolve your issue.
Most likely the memory removal will resolve it. Please let me know so I can be sure this helped.

The fax shows a messages saying "open heat error"


On this machine, you may have a fuser assembly that is bad. Replace the fuser modual.
If this doesnt work, then the main board needs to be replaced.
Also what most people forget is the fuser fan. Sometimes it turns slow and you will not even notice it. It might not even turn at all.
Replacing the fan will solve most problems, but if it still does not turn on, Look on there to see if it has a small circuit board on the fuser fan, replace it too.
if all else fails the main board needs to be replaced.
Good luck

Need to replace the fuser unit kit in a xerox m20 copy machine


First unplug the machine.
Open the right side door. there are four screws to remove. Unplug the two plugs to it.
Pull out the fuser modual.
Insert the new fuser modual, and release or flip the green jam tabs.
When put on the four screews make sure not to over tighten, just a gentle snug is needed.
Close the door, pug machine, and turn it on.
If the fuser fan is not working, this can cause the fuser to over heat again. Make sure the fan is truning by viewing it from the back.
Good luck.

Main Unit Cover Open


With the front door open look at the inside /right side about half way down . There should be a stub of plastic molded into the door . this should push a switch when teh door is closed. if not you may need to "extend" the stub somehow as to activate teh switch. I have a short piece of tubing over the stub to get about 1/8 inch of aditional length. Works great.

What is the expected life of the M20i, before things start to break down. ie: scanner head etc..


This is a very good machine. The self life for the machine depends on Xerox when they end the service life.
The Copy machine is like a car, as long as you keep up the repairs and replace the worn out parts, it will last for a long time.
What you have no control over is if the plastic starts to fall apart due to time. Especially in the main frames. Stress cracks on parts that cannot be replaced.
Otherwise it can go on for a very long time.
Good luck.

Permanent warming up message


When you replace a power supply for this machine, it needs to be the correct power supply for this model. If you have the old one, check to make sure the right power supply was ordered for this specific model.
Because I cannot see the display, and we only know what it is saying, the next best thing would be to see if the fuser warmed up at all. Open the side door and gently feel the fuser frame to see if it is warm at all. Do not touch the Fuser roll; it is hot even to the slightest touch.
If it is not hot, make sure all the plugs were correctly plugged into the power supply.
On this problem there can be other factors that can cause warming up.
First, the fuser assembly may be defective and needs replacement.
Second the main board may be gone out.
And last if the machine has memory chips in the back, unplug the machine, remove the small cover from the back and unplug the simms chips and reseat them. Plug in the machine, then power it on.
See if the machine will go to a ready.
If not, possibly the fuser, or main board, or both. If the main board or(and) the fuser assembly is replaced,
MAKE SURE THE CORRECT PART IS INSTALLED IN THE MACHINE.

If all else fails, Place a Xerox Service Call on the machine before it gets too expensive in troubleshooting the problem with purchased parts.

Changing print properties shuts down all open programs instantly!


I would first of all Go to the Xerox.com site and go to Drivers and downloads for the M20i and install the newest firmware. I believe the current version is 3.4.
I believe your problem would be resolved in loading the newest machine firmware.

Broken Glass on a M20i


1. Oprn the front door, as if to replace the toner and remove the 2 screws above the toner and drum.
2. Turn the machine around. Disconnnect the one connector to the document feeder. A beige molex connector, lift and remove the feeder.
3. Remove the 6 screws from the back cover, remove the cover.
4. Disconnect the white ribbon cable and black connector with red wires attached to the upper part of the main board.
5. Under the scanner body, on the rear of the machine, locate the 3 screws that hold the scanner to the frame. One on the right, on in the middle and one on the left.
6. Grasp the scanner from the sides and pull back to release the scanner tabs from teh frame.

Once the scanner is removed you then have to remove the 3 screws holding the control panel to the scanner, then the 5 screws that hold the frame holding the glass. I am not sure where you can get that glass. But do a google search for "the parts drop". Give them a call, ask for Britt and see if he can come up with one for you.

Brother laser mcf-8440/ machin error 7a


For the error code "7a" to be fixed permanently, you need to ensure that the main PCB is fine and is working in good condition.
If the error code is caused due to malfunctioning of the main motor, then you need to check the whole setup by connecting it with another motor.
In this case, make sure that there is no mechanical load present on the main board.
While fixing this error code, you will notice that the motor runs slowly initially and then picks up the speed later.
