It may be possible to 'temporarily' bypass the cartridge error messages for emergency printing purposes
only or you can also try and reset the printer to see if the error condition clears. Refer to procedures
below.
C. Cartridge Error Bypass Procedure (this procedure has not yet been validated for the 1610 printer
model - please advise if it 'temporarily works for you):
1. Depress BOTH arrow keys simultaneously.
2. Press the Left arrow key.
3. Select the OK key.
4. Press the Left arrow key. The "Service" menu should be displayed (or Press Right arrow key and
enter the ‘Underware’ menu)
5. Navigate until you locate the ‘Checksum’ menu. Select OK.
6. Press Cancel 2-3 times to exit menu from service menus.
7. Attempt to send a print job to the printer. If successful, please note this action typically only
allows 1 single print job to come thru at a time with each ‘Checksum’ clearing action.
D. Printer Reset:
1. Unplug the power cord.
2. Press and hold the OK and CANCEL buttons on the front panel keypad.
3. While still holding the buttons, plug the power cord back in. Continue to hold the
buttons for two seconds, and then release both buttons.
4. After a few seconds, the screen will display the message “Deriv Clear” confirming that
the reset is done.
*Many cartridges eventually do encounter problems or failures, especially after their original ink is gone
and they are re-used, and this is often unrelated to the refill process. The “Incompatible Print Cartridge"
/ “Print Cartridge(s) Problem” / “Check Print Cartridge” / “Remove and check cartridge on left (right)” /
“Refer to printer documentation” / “Incorrect Cartridge: Black print cartridge inserted now is not
intended for use in this printer” / "Cartridge Not Intended For Use In This Printer" / “Print cartridge in
right stall not supported” error message is typically indicative of failed micro-electronics internal to the
ink cartridge(s). In addition, It is common to have a marginally performing ink cartridge (which was
performing ok before) in the adjacent slot (i.e. color), then when a marginally performing cartridge is
installed into the other slot (i.e. black), both of the ink cartridge(s) then get flagged with electrical errors.
Please note this type of failure is quite rare with an ink cartridge that that has only been refilled once or
twice. Severe cartridge errors are primarily caused by an electrical breakdown at the cartridge’s nozzle
