One of my customers went out on their own and bought this. It had a foreign plug on it, Australian I think. I changed the plug and the machine seems to have no other issues except this jam. I just got hold of a service manual today but haven't had time to open it. The paper in the adf stops at the slit glass every time. I assume it is a sensor and will figure out how to access service mode and test. I was wondering if this is a common issue, or familiar enough that someone could guide me, or offer a tip. I have zero experience on Sharp except for a couple of drum changes on smaller machines. I guess I will train myself on this one. Any help would be appreciated.

Re: Mx4110 adf jams at slit glass.
Does it have an RSPF or DSPF? The DSPF has been modified to prevent SPPD2 misfeeds (MX4112N - MX5112N563.pdf), and both DFs have modified sensors (MX4112N - MX5112N639.pdf).
The sensors were modified due to regular faults (from VHPGP1A73A+-18 to VHPGP1A73AR-1).
Check SIM23-2, if the original jam locations are always at the same sensor, then it will changing. -

Re: Mx4110 adf jams at slit glass.
The document feeder is a rspf. I found how to engage sim mode. However I am still missing something. I was trying to test the sensors. In sim mode, I selected the second option, for the doc feeder, and then the second choice to check sensors. At this point I am on a screen that shows sppd1 and others. I can do nothing on this screen. The arrows are faded out. Not sure how to check good and bad. I am so used to the Konica's. Also it does not allow me to select output options. Paper is coming out the right side. When I bring up output options, it does not give me another choice.The greatest enemy of knowledge isn't ignorance, it is the illusion of knowledge.

Re: Mx4110 adf jams at slit glass.
To check the sensors you need to move the flag to activate the sensor. When you do this the corresponding sensor should change state in the display by getting highlighted with a dark box. The arrows are grayed out because there is only the one page to show the sensors. You will need to use the green knobs to move the paper through the paper path to test some of the sensors. I am not sure about your exit options. Is there any finisher on the copier? Maybe a picture will help when accessing output options.Comment

Re: Mx4110 adf jams at slit glass.
thanks. I read the bulletin about the sensors. I am assuming !1 is bad. The paper stops every time in the same spot. The machine has a finisher on it and I am pretty sure when I changed the plug, paper came out in the finisher. When I went back it is shooting out the right side. I may be wrong about that, as I have had a lot of shit calls lately. I am most confused about the power issue. I would have thought a machine from another country would throw fuser codes, but none have been seen. I pulled up a chart of plugs and I am pretty sure it is not austrailian, but I can't seem to remember exactly what it looks like. It has really been difficult lately.

Re: Mx4110 adf jams at slit glass.
Print a sim23-2. This will give you a list of the jam codes. In your manual there is a description for the jam codes in the troubleshooting section. Quick way to see a pattern for jams.Comment

Re: Mx4110 adf jams at slit glass.
Also, simulation 22 - 6 will give you all the maintenance and diagnostic information. Be sure to print this too and keep it for your historical service records. Also, that machine is fantastic. You wont have much trouble with it.

Re: Mx4110 adf jams at slit glass.
Did the plug look like this?

If so it's not foreign it's a NEMA 5-20r plug as the machine draws more than 15 amps. Still 120v which is why it's probably working. The original cord should be installed and the wall receptacle changed to accommodate as long as the breaker is rated for 20 amps.
As for the jams you should definitely print a 22-6 (Sim 22-6 then execute) and get a list of jam codes which should help pinpoint the issue as was previously mentioned. Does the page have any creases or ridges indicating something blocking its path?Comment

Re: Mx4110 adf jams at slit glass.
No, I would recognize that one. When I looked at a chart of world plugs, I didn't see what I think I remember. The guy who bought it, who I haven't talked to yet, came to the conclusion as to where it came from. When I first looked at it, they had cut the end off a US cord and twisted the wires on to the prongs on the plug and taped them. I for some reason did not save the old plug.The greatest enemy of knowledge isn't ignorance, it is the illusion of knowledge. Stephen HawkingComment

Re: Mx4110 adf jams at slit glass.
It is common for the sensors to go bad on all Sharp RSPF models and I believe they all use the same modified sensor as mentioned in an earlier post. ALSO>...these is an odd sticky residue that has been showing up on the feed roller shaft and can be found by touching the shaft with the roller removed. It is also in the one way pulleys on that shaft usually. I have seen this cause all kinds of delay jams, and have even seen the adf jam visually without the mfp recording any jam on the 22-6. Every mfp I go to with an rspf I remove the adf feed roller and pulley and clean them with alcohol and put them back and the issue is usually fixed. Another sign is uneven wear on the rollers but I dont always see that. Hope this helps. repn1999@yahoo.comComment
