Machine does not print code 46 comes on? can i fix it myself.

On the display the message came up to call for service with the code SC546what can I do to fix it myself. the machine is not working for printing. machine is ricoh modle SDm645

The messages unable to print, unable to clean, unable 36, error 46 and error 32 are all print head errors.

1. Remove all the ink cartridges from the machine
2. Clean the contacts on the cartridges as well as inside the machine itself with a small amount of warm water or alcohol on a cotton swab until no ink comes off on the swab.

Note: if any of the other cartridges are low, empty, leaking or bulging replace them

3. Then turn off the machine and unplug it for 70 seconds
4. Plug it back it and wait for the insert cartridges message
5. Insert the cartridges and check to see if the problem is still there. If it is it means the print head has failed and in order to fix this the print head inside the printer needs to be replaced. The print head is the part of the printer that puts ink from the cartridges onto the page

Unfortunately this can sometimes cost more to replace then the machine itself.

Unplug the printer from power cord.Press and hold the "menu" button, then plug the device.You'll see on the LCD screen a "machine error" code.If this code is 40,41,49 or 4F the print head is defective.If the error is 48 - defective print head cable or circuit board.If the error is 50 or 51 there is error in Purge unit and printer require service.If the error is 46 the waste ink tank is full.Follow this:
Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.This will reset the purge count value. Then restart the printer, hopefully without the annoying cannot clean message.

Here is the answer to the Machine Error 46 (have just fixed my own MFC210C):


Machine Error 46 – Purged Ink Box Full MFC620CN/420CN/410CN/210C and FAX2440C

The machine counts all purge (cleaning) operations in order to prevent the internal ink absorber box from overflowing with purged ink. An “initial purge”, for example, advances the purge counter by 187 + 420 = 607. When the purge counter approaches 6400, an internal "Machine Error 46" is generated. Further purge operations are prohibited, and therefore the printer becomes unuseable.

When an internal Machine Error 46 is generated, the user will see an “Unable to Clean” external message and will be unable to use the printer. The “Unable to Clean” external message can relate to many different internal error codes however.

The user can establish the internal Machine Error Code as follows: pull the mains cable out of the machine (power off), hold down the Menu/Set key, re-insert the mains cable into the machine (power on). The internal Machine Error Code will be displayed.

If there is a Machine Error 46, it is necessary to dismantle the printer, replace the ink absorber box (or possibly break the ink absorber box open and clean its absorbent sponges under a tap), re-assemble the printer and reset the purge counter to zero.


Resetting purge counter MFC620CN/420CN/410CN/210C and FAX2440C

1) Enter machine maintenance mode (on MFC210C all four photo/copy/fax/scan lights flash in maintenance mode). Care is needed in maintenance mode, otherwise critical settings may be inadvertently corrupted.

FAX models with numerical keypads: Press the Menu/Set, *, 2, 8, 6 and 4 keys within two seconds. (if you fail to complete the correct key sequence within two seconds, press the Stop key to try again).

Other (non-FAX) models: Press the Menu/Set and Black Start keys. Next press the “up arrow” key four times to enter the maintenance mode).

2) Press the 8 then 0 keys in the initial stage of the maintenance mode to call up the machine's log information list (function code 80).

3) Press the Black Start key several times to scroll through the log information list to reach the purge counter. The purge counter is the 25th item in the list.

4) Press the 2, 7, 8, and 3 keys in this order to reset the purge count to zero.

5) Press the Stop/Exit key to return to the initial stage of the maintenance mode.

6) Press the 9 key twice to return to the standby state.

Carry on printing !!

thanks.

hth,

ervice code SC 46-01 is indicated.
Solution:
PROBABLE CAUSES: This code is triggered by the lack of 12VDC being supplied to the print head.
Please check the following:
1. Check for 12VDC at the Image Control Board. If voltage is missing, the main power supply may need to be replaced.
2. Also check the voltage being supplied to the copier; poor wall voltage may also cause this issue.
3. A less likely possibility is a faulty print head (write unit).
are a technician?
if not am not sure if this somthing you want to do your slef with out service manual
