I have Gestetner DSM622 SP, Iam getting Errer code SC546, can someone explain me thanks

sc546 is a fuser temperature detect error. One or both of the thermistors most likely need to be cleaned or replaced, but you will have to go into service mode to reset the code once you do that. You should contact your local service technician or Gestetner dealer, as they can easily fix that problem.

Follow the next steps carefully and the error code SC546 will disappear.
Press the following keys by this order:

1. press the (yellow key) [Clear]
2. press then the numbers on the numbers key by order (1)-(0)-(7)
3. press the red key (cancel) [C] and hold it pressed for about 5 seconds.
4. on the screen will appear another menu different from the one
you are
familiarized it will write up in the left corner [service menu],
(if the service menu do not appear repeat the procedure again).
After this menu will appear turn off the machine from the red switch which is located somewhere in the middle of the machine and just by the left corner (the turn off switch-plug) wait for 10 seconds and turn back on the machine by the same switch-plug.

After this the error code SC546 should be disappear.

Please Answer does this was helpful for i to know does the problem has disappear or i should post some other information.

SC541 - SC-555

These codes mean you are having a problem with your fusing unit. The section of your copy machine that has to heat up before you can make copies. It runs at a pretty high temp because it has to melt the toner and press it into the paper as the copy moves through the machine. Depending on the code, your machine is either taking too long to warm up or it is overheating.

The most common reason is a build up of hard crusty toner on the temperature sensors. This tricks the machine into not seeing your fuser warm up fast enough. Most of the time you can reset this and continue to use the machine but expect the code to come back down the road. You can also get codes if the room the copy machine is in is too cold when you start up the machine. Either a cold winter day or even a summer day in a room too cold from air conditioning.

Some machines require you to enter a service code to reset a fuser/fixing unit error. Some only require you to enter the service mode, then turn the machine off / on using the main power switch. The main power switch is the one you have to rock to the off and rock back on, not the little button you press for power to come on.
To enter the service mode press the following keys in order:
Clear modes
then press and hold the stop key
You will see the display screen change. At this point turn the machine off / on to reset the code.
If your machine does not have an LCD display screen you should have seen the copy quantity
display change to a flashing zero.

Some machines will need to add a step to the above instructions.
Once the LCD screen changes, select the "SP Mode" selection from the touch screen.
Enter 5810
This is the Service Program (SP) that resets Service Codes (SC-###)
You will either have to select 1 to accept or select the touch screen button to activate this SP.
After you do, turn the main power off / on to reset the code.

If you try this and the code still comes back on, you have an electrical or mechanical problem that you will need to call a service company to repair. The reason for making this code so hard to reset is a safety issue. If there is a short in your fuser unit it can cause your machine to over heat and possibly cause a fire. There are thermistors (temperature sensors) and thermostats (temperature fuses) that will keep your fuser from overheating. If either of these devices are worn out, you will not be able to reset the code and will need to have your fuser serviced.

Service code sc546 what do we need to do to fix this problem?

Try to go into service mode to reset the code...
Clear yellow botton
then press and hold the red stop botton till the display changes and then turn the main Power switch Off then back ON... You do not have to do any thing in service mode, just get to that display.... Don't change anything unless you know what you are doing. sc546 has to do with the fixing unit. You may be able to reset it.

Lanier 5645 copier - Code sc546

Try this press the "yellow/ca" botton, then enter 1-0-7, then press and hold the "red" stop" till the display changes. Once, it changes turn the Main power switch OFF. Not the one on the control pannel. Let it power down then turn it back ON. If the problem is still there try to turn the copier Off again and unplug the sorter/ finisher and turn the copier back ON. Is the problem gone, if so you may have to get a service person come in and repair the sorter. Good Luck.....
