Brother mfc 7340 self diagnostic error


Most likely your fuser lamp is damaged, the fuser would need to be replaced, but bringing it in to an authorized brother service center would help. Its also possible its the LVPS (low voltage power supply) and mainboard, but probably the fuser.

Xerox workcenter m-133 and the error code is 010-313 and how to fix it


Perhaps the info here might be of help to you...



Fuser Related Status Codes & how to reset them:

C123 style (C123/128/133, M123/128/133, Pro123/128/133) 010-313 Fuser Control Thermistor failure (open Control Thermistor) 010-314 Fuser Side Thermistor failure (open Side Thermistor) 010-318 Fuser temperature did not rise quickly enough during heating cycle 010-320nakeder Overheat (must be reset from diagnostics by resetting NVM (Non Volatile Memory code 744-220 back to "0") * 010-327* Fuser took too long to warm up (must be reset from diagnostics by resetting NVM (Non Volatile Memory code 744-220 back to "0") * * C123 style: Resetting Fuser Codes (010-320, & 010-327) Accomplished by resetting NVM code 744-220 to '0'... First enter UI (User Interface) Diagnostic Mode: Hold down the '0' button for 5 seconds and then press the 'Start' button while still holding the '0' button. The machine will prompt you for a Password. Enter the default Access Number: '6789' and press "Confirm". The colors on the display will be reversed to indicate that you're now in diagnostic mode. Next press the Dual Heat Lamp Assembly (C123 version) www.partsdrop.com 201-387-7776 Page 4 of 5 AC Connector: C123 version "Log In/Out" button on the Control Panel. Select 'System Settings', 'Common' Settings, followed by 'Maintenance / Diagnostics'. Now you will find the main menu includes one choice called "NVM Read / Write" (NVM is Non Volatile Memory)... Now you can enter your "Chain-Link" code (in this case 744-220) and press 'Confirm / Change'. The current value will appear (if the machine is in a fuser fault condition, the value will be set to "1"). Select the "New Value" column and input your new value ('0'). Select "Save" and the new number should now appear in the "Current Value" column. You can turn the power off and back on at this point. The machine will attempt to warm up the fuser again. If the condition which caused the fault in the first place is still happening, the Status Code will return after a few minutes of attempting to warm up. C118 style (C118, M118, M118i) U4-1000 (U4-1) Fuser failure (did not come up to temperature in time)... must be reset from diagnostics (NVM code 50-20 must be reset to '0')*. U4-2000 (U4-2) Fuser over temperature.... Must be reset from diagnostics (NVM code 50-19 must be reset to '0')*. U4-3000 (U4-3) Fuser thermistor circuit is detected as being an open circuit. * C118 style: Resetting Fuser Codes (U4-1 or U4-2): Enter diagnostics (from the powered on state, hold down the '0' button and then press 'Start'. The display will change to opposite colors to show you it's in diagnostics)... Select 'Chain-Func' in the 'CE Setting' screen by using the 'Select' button, followed by 'Enter'. Select "NVRAM R/W". Enter the "Chain" (in this case '50'). Next select "Func" (function) by using the "Select" button. Enter the "function" ('20' if you're clearing a U4-1 code or '19' for clearing a U4-2 code) followed by 'Start'. The current value for that memory code (50-20 or 50-19 in these cases) will appear in the "Read" column (if the machine is in a U4-1 or U4-2 status condition, the value will read as '1'). Change the value by pressing the "Select" button at the "Read" column to switch to "Write". Enter a '0' for the new value, and then press 'Start'. Finally, select "Write NVM". You'll probably be well served by being able to test the lamp and thermistor circuits from the AC Connector so you know what you're looking to replace before you even rip into the fuser. On the C123 & WC-5225 versions, there are slots for 8 pins (2 rows of 4 arranged vertically). Pin 7 is on the upper left and Pin 8 on the upper right is empty. Pins 7 & 1 are one of the two Heat Lamp Circuits. Each Heat Lamp Circuit goes through its respective half of the Heat Lamp Assembly, and then through both thermal fuses to the return wire (pin 7 is the return wire which is common to both heat lamp circuits). Pins 7 & 3 are the other Heat Lamp Circuit. If either Thermal Fuse is blown, neither lamp circuit will conduct. If one circuit measures good and the other measures bad, then the Heat Lamp Assembly must have failed. The Thermistor circuits for the C123 are between Pins 2 & 4 and Pins 5 & 6. If you set your meter to 200K ohms, you can measure the Thermistors... they should measure a high resistance and then if you were to warm up the Thermistor's head, the resistance should begin to drop. These Thermistors are unusual in that the heads are ***** (no yellow kapton tape). www.partsdrop.com 201-387-7776 Page 5 of 5 AC Connector: C118 version The C118 fuser's AC Connector is shaped the same as the C123 version (slots for 8 pins) however there are only 4 pins actually present and they numbered the pins differently for this one. On this one, Pin 2 is in the upper left corner and Pin 1 is in the upper right. On this connector, Pins 1 & 3 form the Heat Lamp Circuit. The Thermistor Circuit is between Pins 2 & 6. Hope this turns out to be valuable information for you. It'd be a shame to replace one of these fusers and then throw out or return the used one without at least inspecting it for the possibility of fixing it for the next customer who needs one. Be a green-tech and fix'em when you can. Happy Repairs everyone!

Where is the fuser located on the brothers dcp 7020


Just below the slot where the paper exits into the catch tray. It may feel a little warm in the fuser area.
Thanks

Machine error code 6A what that means?( Brother mfc 8440)


I argued on the phone with a BROTHER REP. that he should give the codes and directions to reset the machine, he refused time and time again, saying that this means physical damage to the machine an re-setting it is impossible to help, but i insisted, and it did fix the problem and the error went away.
here is what you should do, unplug for 10 sec. press and hold on the menu key while you plug it back in untill you see the screen "parameter init" press 99 and wait, this is what i did and it fixed the problem !!

Error 77


Try opening the front panel, removed the toner and close the panel. The printer should try to warm up and then say to open the panel door. Then open the door, insert the toner, clos it and the machine error should clear.
If not ---- power off the printer for 15 minutes and power back on again. If that fixes the problem then OK. If not then go into maintenance mode -
Press and hold the menu/set key while turning on the machine. Wait until it comes completely up before releasing. It should say Maintenance in the display.
If not press function,*,2,8,6,4 within two seconds. It should say maintenance in the display. Or on some machines Menu,*,2,8,6,4 within 2 seconds.Once you get it into maintenance hit 91 to do a parameter reset and than 99 to get out of maintenance.
If this corrects the problem then OK but you may have a failing thermister in the fuser. If the problem happens again then change the thermister. If the reset does not work then either the thermister or the fuser lamp has failed. In rare cases there is a poor connection with the cables to the fuser.
You will have to reset the parameter again after replacing the fuser if you need to replace the fuser or repair it.

Brother 7020 printer "fuser error"


The fuser has failed and needs to be replaced. If it is still under warranty Brother may cover it. If not you will have to take it to a Brother Authorized service center. It may be possible to find a used one on Ebay, even if its just for parts. Some of these smaller machines require extensive dissassembly to replace the fuser and shouldn't be attempted by a novice.
