3 sharp machines with F2-40 codes. Please give your input

[axyun]

In the last 2 weeks have calls from 3 new customers with Sharp machines. All with F2-40 error codes.

The first machine was an MX-M354N which was throwing developer all over. A new dv unit had previously
been installed as I saw the bill. Developer had been changed twice within several weeks before I got the call.
I changed the developer, process unit and drum. I noticed the other day that it was still throwing developer
as I notice a little on right side feed area. I am going to check transfer unit springs etc.

Then got call on MX-2610N with F2-40. Didn't see any dv on mag roller and assumed some had been pulled.
I changed developer and ran 25-02 and it went to ready but noticed abnormal numbers in 60s and 70s on black
dv unit. I never did check the density sensor so it could be that or a problem with mag roller. I ran copies which
horrible. Almost like a negative. Ran color and was better but with black background. Definitely looked like a voltage
issue. I had taken all toners out when I did the 25-02 , not just the black. The procedure was not exactly clear to me.
I entered the mode and clicked on the ver on the screen that came up. I entered the 25-02 but was not sure how to
proceed. The SM said to select which dv unit but I did not see that screen after entering 25-02. I saw screen with
a choice of MONO or COLOR and assumed to choose MONO to get to next screen to select black dv unit. I will cvheck
SM again. I ran the 25-02 a second time, hoping for better results. Again, I removed all toners.
Eventually, machine went into toner replenishment mode and
then I got another F2-40. I just ordered a new black dv unit and expect it Thursday. Doing call again next Tuesday.
Any advice is most appreciated.

Today I got a call for an MX-5110n with F2-40. Customer says someone was there and said developer was pulled
out and they need developer and 4 drum units as they are worn. I am to go there tomorrow and am picking up
MX-51NVBA dev. and just got SM and PM . Again, any advice and information on these machines is very much
appreciated.

wow man. sometimes you just have to take one call at a time. on the 354 check process unit charger. broken coronas pull developer. on the older b/w there were springs behind drum unit and right door that had to be stretched from time to time. on the color machines when you replace or install developer leave front door open with toner removed, power on, clear counters, enter 25-2, close front door, press either mono or color (doesn't matter, they both mean start). the newer black machines are particular about their toner concentration. if it doesn't land right, sometimes you have to do dv check disable, run sky shots, and run 25-2 again to lock it in. hope that helps, good luck.

Thank you Sharptech1. On the 354 i installed new process which has new main charger. I will check all springs.

If I need to do a dv check disable do i remove the toner or does the disable check prevent toner from being added.

Is it a bad idea to remove toner and do a 25-01 to see what the output reading are to see if they are within acceptable limits before doing 25-02? Frank`

if your 354 is dumping dv may be a bad hvt although i have never seen one go bad. if your concentration levels are overtoned like 70 when running 25-01 power off remove toner power on with front door open run sim 7 dv check disable run sky shot sets of about 20 check concentration with 25-01 until you get within 125-128 range and run 25-02 to lock it in

I have replaced the right side door to fix 354 and similar models from pulling dv. I think sometimes people lean on them removing jams and crank it off center. Id even say its pretty common for that series. The color machines are usually just the density sensor for that error.

When you changed the door, did you use the same transfer assembly or swap the whole door with transfer asm from another machine? I was going to check transfer asm springs, etc.

Also changed developer on MX-5110N after cleaning out and ran 25-02 successfully. Machine is fine except for wear on couple of drums. Frank

I have done it using the original transfer assembly.

If you have 3 copiers with the same F2-40. It may be possible that the toner was left on the MFP when the developers were calibrated. This will caused this error code after a while and it will also go thru a lot of developer. I would also check your toner supplier.

on the 354 make sure the machine is totally level by placing a leveler on the glass . Ive had a few of these machines that when off level will concentrate the dv on either the front or back of the machine and will make good copies but throw the dv out. Had one of the junior techs replace everything on a 354 before i went to go check on it and it was far out of level. after leveling it out havn't heard back since.
