[Error Code] Won't run MFP-SB-083R without Error141 Phase Yellow Front or 146 Phase Yellow Rear.

Help!

Have run SB-083R on MX-3501N and had no problem. Went to run it on a machine that has yet to be fully calibrated (per the bulletin on MX6201N) and now, besides not making it past step 9 (Maintenance, Service Call or Firmware Upgrade versions of bulletin), it's popping up error 141, 146 (going back and forth between the two everytime it's run) on sim 50-22 (step 5 of bulletin). I've run sim 50-22 in "ALL" and separately in "Regist" and "Drum Pos" modes of the adjustment with no joy. Can anyone shed some light on why these adjustments are mental torture?

Thanks in advance.

do adj 6 in the service manual first b4 doin sim 50-22 this will adjust all the led heads in the lsu first

What model mx3501 or mx6201, two different, but alike beasts? (Silver there are no LED heads in either of the two listed models.... (thank goodness ARBC GRRRRRRRRRRRRRRRRRRr)

It's the MX-6201. I gues I didn't make that so clear, much like the adj. process for Sharp Color. I've been tortured b4 but not like this. The Konica-Minolta 5001 was incredibly complex to balance. It had all this stuff plus fuser adjustments (eight of them) that were done but the difference was, they were only done at PM's or svc calls with CQ probs. Thanks so much for the reply. Have a good one and hopefully you've got some more enlightenment to pass on about this adj procedure. I've worked Ricoh, KM, Sharp and Toshiba color (the sharp was about 5 years ago).

Thanks for the reply to my thread. I'll try that. At least this isn't Ricoh color. The 6513 (revolver mach) had a bevy of adjustments as well. You even had to adj fuser with every PM.

yeah i know no led heads but u get the point the precedure i referring to had to be done first b4 the 50- 22 it alligns all the lasers

On this unit, the laser adjustment is ADJ 8 or SIM 61-4. ADJ 6 are high voltage adjustments. Do this before 50-22. Next, I do 44-13, with calibration jig, 44-2, 44-6,44-26, then 46-24 and 67-24 for print. If the DV is new run 44-27 to clear the data BEFORE running 44-26. As all your issues are yellow, i would start there. What does the yellow drum unit look like? Run 25-1 and see what the readings are for yellow; are they way out of whack..below 60 or over 160?

my bad thought he was working on a 3501

Thanks Mojo. I just got onboard at this sharp dealership and am new to sharp color. I've yanked a drum and yellow Dev unit from another 6201. Along with these adjustments, I'm hoping to cure a machine that's been a headache for the dealership for 6 months. Of all the color machines I've worked on, yellow always seems to be the tweakiest color. Wish I had a loop but at least it's on order. The orig problem on this was eneven color density front to back. It was only when copying (per the customer and tech that was shootin' it). Then it migrated to printing as well as copying. The tech that had been working on it had very limited color experience and this machine is not a good intro mach for any black and white tech to work on. Thanks to you and Silver for your replies to my thread. If I can ever help you out, give me a shout. I'm an electrician as well. Have a good one!

The 6201 and 7001 are very touchy in many aspects. Expect flat spots on the fuser rolls. It is an easy diagnosis as you can hear the fuser chug chug chugging along. They are VERY touchy with high humidity. I am currently fighting a 7001 running in a room over 80 degrees and high humidity, not to mention the cheap paper. Always getting a toner build up in the DV units from humidity. I increased the fan duties and lowered the toner prep settings with only limited success. It is moving to a cooler and larger room in two weeks....or so they tell me.

You know as well as I do that any paper with a brightness less than 96 isn't going to give decent color rendering. Anything over 102 will have a cyan tint to it and generally yellow tint under 92. The humidity can get so bad here that paper looks like a topographical map. Of course you don't get transfer (or light gradations) where the "hills" are. You machine is going to misfeed and have copy quality issues until it's in a decent environment. That's a blue whale! I've had a lot of fusers develope flat spots and chug. It sounds like a thump-thump-thump to me. I don't think there's any setting you can do to really help the machine. It's just not designed for that environment. The humidity here in Alabama is insane. It reminds me of Houston (I'm from Texas). We've even told people to get some gallon bags at the dollar store to keep there paper in and that helps. Some machines have humidity sensors that will kick on the fans more often. I don't know about the Sharps yet. I'm on my third week here. Thanks for your feedback. I'm probably going out tomorrow to battle the beast. I've already gotten the adjustments to run on a 3501 (it was in the shop for a couple of months with a loner at the customers). Hopefully, these adjustments will fall into place and we can keep the customer. Thanks again and have a good week.

Mojo,

I'm reading this as do Sim 61-4, then 44-13 (w/jig), then 44-2,6,26,24 and finishing with 67-24 prior to 50-22. Is this correct?

[mojorolla]

Sorry for the delayed response.One full week of vacation. Run in this order:
61-4
50-22
44-13 (jig)
44-2
44-6
44-26 (If developer is new run 44-27 to clear half-tone target, then run 44-26
46-24 (copy)
67-24 (print)
