When the ROM Error message is displayed on the control panel, this will indicate an issue with the Flash DIMM on the Image Processor PCB.

re-flash the system software/or replace the DIMM Assembly.
When replacing the DIMM, you may be required to flash the system software to it's latest version.
iR 1600/2000 FG6-9978-000, Dimm assembly.

As a temporary work around, power on the iR while holding down the STOP key. This may boot the iR to a ready state and copies can be made.
Service Mode=Additional Functions #

Clean the beaneath the copy glass, clean the laser unit, polish the toner cylinder, and replace toner cylinder cleaning blade.

it is very possible the dark line on your copies are being caused by the drum. it will all depend on how many copies are on it but without seeing one of the copies the best guess i can make is the drum.

MY COPIER IR 1600.AFTER HAVING REPLACED PARTS DRUM UNIT +ORIGINAL TONER IMAGE PRINTING IS VERY POOR .WHY

First normaly copy first side, then take copied paper and set it in bypass tray, when you do thath, the copier ask you for paper size and type, choose correct sett. and confirm with OK.The side on wich you want to print must be face down in bypass tray.

You may be low on toner

* Disable toner save by change in printer driver.
