Have a 500 that keeps stopping and adding toner. They are running high coverage B/w prints, it only runs about 8 pages before it stops and adds toner. Any ideas.

there is a simulation to change the adding toner cycle longer out.

HAD A 300CI DOING THIS HAD TO REPLACE ENGINE BOARD AFTER "HELP" SAID MAIN, DIM, DEV UNIT, DRUM ETC. JUST WENT ON A HUNCH FOR ENGINE AND FIXED

That's a little concerning.
Normally a simulation 21 corrects the problem.

Weird!

Update to ver 11 firmware
change sim 147(operation mode) to 0
change sim 486 to mode 1
run sim 464, select AC calibration, set all colors to on, then execute. you will have to restart after this.
run color reg
run color calibration,
enter sim 410 and press continuous adjustment,print and scan the 3 pages
run sim 412 and press default value, print and scan the 3 pages

this now a mandatory MCP on every taskalfa over here and does seem to straighten out a lot of weird problems.

Make sure the machine is clean and vac'ed before you start.

RIGHT JEZZY, TRIED THAT ALSO, WORKED SHORT TIME BUT WENT RIGHT BACK, UNTIL CHANGED THE ENGINE, NO PROB SINCE DEC '10. NOW HAVE A 500CI, SAME THING HAVE TRIED EVERYTHING SAME AS BEFORE, NO DIFFERENCE. WILL TRY DREWSUP SOLUTION, WILL POST LATER

hey drew were did you get that information from? was it a tech bulletin, just asking because we have not gotten an kma update here that i have seen. regarding this problem

this was sent my company from KM

I'll trade you that little nugget for anyone who can post the welcome screen lockup troubleshooting guide, it's not available over here.

this what your looking for

Shep can u re post, the file shows broken .

Check MM157 Dev Drive time for Black.If this value is over 5667 then the unit needs replacement.Update the firmware before replacing the Dev Unit.The current firmare does address the drive time issue causing excessive cycling and developer crash issues.I've resolved several by doing this.
