I have had a few here recently, on low volume newer machines (12K or less, less than 90 days), setups went fine, on site a power reset clears it (without sim 14). The transfer unit its self cams fine (by hand) and when running sim 6-3 (both clutches) Have removed and checked both clutches (dinky little suckers) and can feel no excess drag in the drive units. Checked both photo sensors in the rear of process cavity in sim and they check ok. Checked all connecting gears and rear unit to frame contacts. You guys and gals think I'm missing something?

Where the heck is my spring hook? -
I haven't had that code on a Frontier as yet, and I know there are no bulletins on it yet either for those models.
You seem to have done everything spot-on so far, so next would be to install a new Transfer Belt. I have had a few transfer belts fail after 20K, maintly due to loud noise, blade flip & belt damage or surface beading, but I'm yet to see L4-06, as common as it is on the bigger MX machines.
Try a new belt unit for starters. Please let us know how you get on with this one. -
I (on my most recent call, out of two at this cust. 12 days apart (long drive, non maint)) was for a install transfer belt message that happened in the middle of a job (copy, no network yet) they had a second l4-06, but must have cleared it with power cycle, a few days in between (gotta love sim 23 and the web log) anyway, power was off at arrival, powered on ok, did use a transfer belt from another lightly used machine. after double checking drive sensor and grears, (less than 5k), both units in great shape, good belts, no blade problems (havent had any B or C frontiers with blade trouble yet) (yeah!) They went nuts using yellow as starting powder. Same for you guys?
Wall Ac ok, just kinda stumped, maybe the firmware only allows for one rotation to fail before coding out? Justa guess.
Weird thing is I haven't had really any trouble let alone l4-6 with my C machines, and they have more to cam!
P.S we are feild rebuilders (fyi) (by manual specs), having a whole unit around is a luxury.
What do you mean by surface beading? When foreign material makes a outward bump in the belt?Where the heck is my spring hook?Comment

OK, something to go on there.........
If this happens during a job, I would bet its the belt up/down clutch or the harness/DC power going to it.
Yes, yellow starter powder flows feely here too on the MX-C's. Its good stuff though & works well. There is no mention about timing of clutches for the belt in any firmware revision bulletins, so I really doubt a firmware problem.
It is a real shame you can't carry full units, especially on those Frontier machines. I dont carry anything other than PF rollers for those models in my car, as when a call comes in for one, I grab all new units from the warehouse. Makes the job alot easier thats for sure! (Although I do ALOT of MX unit rebuilds, I know what you mean). I just find the MX-C's work better with a new unit each time. Not worth the trouble you get from them.
When I mentioned surface beading, I was talking about one I had which had developed a very rough surface on the entire surface of the belt. There was nothing foreign inside the belt floating around doing damage, just nothing like the smooth surface a belt should be.
It was quite weird. It looked like an issue with a transfer roller had caused it during normal rotation. I didnt even bother looking into it further, as a new belt went straight in and it tested perfectly fine.
As for your L4-06, maybe order a new belt clutch, or if you want to get really into it, put your meter on the clutch during sim test operation and see if you get any unusual readings every now and then (because its not a regular continuous problem, there might be a power issue).Comment

I have ran into that twice before and both times the transfer belt assy just wasn't seatewd properly. The reason I noticed was beacause the waste toner bottle just didn't look rightComment
-
Yeah, it is highly possible the belt might not be seated correctly, as the damn thing only attaches in with 1/4 turn plastic clips. Nowhere near as stable as the MX machines. Give it a try.Comment

Regretfully, I dont think the customer has removed the belts (or anything else), it was in location for at least a month before issues appeared (rules out a "rough handled" delivery). Haven't been back yet, (after clearing codes with power resets) and basic checks. (non-contract, long drive)Where the heck is my spring hook?Comment

I had a MXB401 that was asking for the transfer belt to be installed when it was. There was also a L4-06 in the log. I took the belt out, played with it and no problems that i could see. After 2 more call backs for it i swapped the entire belt out and that part of the machine has worked fine since.
Bank executives are so impatient
Be nice to see what happens with this. I got a belt i don't know what to do with.
Once i had the clip that waste toner tank is supposed to push back so the T belt can rotate come infront of the waste tank. When that happened it locked up the transfer belt cam. The clip is supposed to stop the cams rotation when it's out of the machine. That also threw a L6-04. Also made it very hard to get the tank out.Evil will always triumph because good is dumb.Comment

I had the exact issue good pick!Comment

I chased random L4-12 2nd transfer error on for a couple of weeks. Replaced REGS_R reg/procon sensor unit and shutter and had same problem. Long story short the Emag clutch driven by the fuser drive unit was slipping. This clutch cycles transfer 2 and has an important job + its tiny. 401's are the most clicky, snappy, plastic, noisey machines by nature, lube transfer 1 and 2 cams seem to quiet them. I'm betting you have a clutch problem.Comment
