Output section problem - Error code H5-01

I have a Sharp AR-M450 copier/printer/scanner. For both prints and copies, the paper stops right at the final roller stage, the rollers being driven by a stepper motor. The copier/printer gives me an error code of H5-01. This is a final stage output error code. There is also I believe an optical switch at this point that senses the presence or lack of the paper. I've disassembled the output stage of the machine, cleaned the parts with compressed air and reassembled, lubing areas that seemed like it might need it, but no luck. Having removed the stepper motor and spinning the rotor, it seemed a bit tight, cogging at the small steps. Any ideas on what might be causing the error code and what might be the primary culprit?

    Thank-you for your wonderful response. I did as you suggested, cleared the error code message and entered simulation mode. The POD2 sensor (the plastic actuator just before the final roller mentioned in my original post) seemed to respond just fine when I slipped a piece of paper back and forth into and out of it. The POD3 sensor (on the outside of the roller) also was checked and worked fine. I again tried to make a copy and the leading edge of the paper again hung just at the roller. Entering the simulation mode again shows the POD2 sensor properly activated. Next step?

    By the way, what’s the easiest way to exit out of the simulation mode?

    Thank-you again for your follow up response. I entered simulation mode and tested the PODs. The POD1 sensor (the plastic actuator just after the fuser) did not respond when I toggled it while the POD2 and POD3 did. I’ll have to get to the disassembly step later today and see if the optical sensor is blocked or the cables are an issue. If you have any further suggestions, those are greatly appreciated. Thanks again for your kind follow-up.

    Thank-you again for your response. I took the time to tear into the machine tonight. In trying to swap out another POD sensor, I damaged that one as I wasn’t aware of how the cable connected – got it figured out now, but learned too late to prevent the damage. I found several suppliers online for the sensor, so I’m just going to go ahead and order several sensors.

    Was also getting a code F1-15 Finisher Unit today when I turned the machine on to scan in some documents. I had seen this before and asked a repair person to change the fan above the finisher unit (it was squealing at times rather loudly due to its bearings going out) and to take care of the code problem as well. After changing the fan, the switch problem went away as well, but then came back several days later.

    When I had the covers off the unit a few days ago, I removed the micro switch indicating the finisher unit is closed properly, sprayed some contact cleaner into it and cycled the switch several times before putting it back in. When I reassembled the unit, I noticed that the finisher unit wasn’t closed as flush as I would normally expect, esp. on the back side near the switch (It’s perhaps been this way for a while, but this is the first time I’ve noticed it as I’m more aware of the machine’s panels fits now that I’ve disassembled many of the panels several times. There was some “sponginess” in the resistance to closing the unit, but the latches engaged and the switch appeared tripped.

    Another tech forum suggested that “F1-15 is usually the finisher tray switch, check the output tray and make sure the tray is attached correctly and hitting the switch ok. If the copy stops in the middle of the finisher with this code, there is an adjustment on the swing belts via solenoid to make more contact.”

    I found a Sharp AR-M350, 450 Service Manual online, so now am more acquainted with the simulation codes you mentioned. Unfortunately, it doesn’t give any part numbers for the finisher switch. It seems like a straightforward micro switch. Any insights on what the replacement part number would be for that item?

    Thank-you again for your help. I will definitely give you a positive rating.

    I have ordered 3 photo sensors (P/N VHPGP1A73A+-1 Photo Coupler/Sensor) at $16.75 each plus s/h from Precision Roller (they appear to have the best stock that I’ve found so far on the Internet). Virtually nobody has any in stock, let alone 3 so it will take about a week and half to get the parts in.

    As far as the finisher door switch for the Sharp AR-M450, the original is made by Matsushita. Here are the specs.

    Single Pole Normally Open

    T105 mu 25E3

    16(3) A250V AC 6A30V

    AM51632C531 03113F

    12A 250VAC; 6A 60VDC


    AM51632C531 is not a Sharp part number and I couldn’t find any cross reference info other than some documents referred to from a Thailand website, those links being dead.

    Switches that should fit and work include the:

    Honeywell V7-6C27D8-048 and

    Omron V-15G2-1C25-K

    Unfortunately the standard lever type of subminiature switch does not come any more in the SPST version. So one has to purchase a SPDT and remove or cover the NC terminal (to prevent accidental incorrect connections). Hope this information will be helpful to others that might be looking for this info.

    The POD sensors came in last night. I just finished replacing the POD1 sensor (along with the one (POD3) I had inadvertently broken) and reassembled the machine. Accessing the wire pigtail to reach the the POD1 sensor was a major disassembly chore. When the reassembly process got to a part where I could run the SIM test on the printer, I did so and the POD1 sensor responded as it should. Finished reassembling the printer and it worked. I'll deal with the other Finisher issue if it shows up again.

    Thanks again for your help, Ttehnik_bdg. You were great.

H5-01 indicates that you have 5 continous paper jam in a row. It's generated when one of the paper feed sensors did not detect the paper, in your case the sensor might be the one that located in the exit section ( POD1 ). This photo sensor might be just covered with paper dust in between the gap housing, the gap is only 1 mm wide. You can check the functioning of this sensor by entering the sim mode 30( main code), 1(sub mode). After entering this mode try activate the sensor by moving the plastic actuator, if the POD1 display highlighted on and off it means OK. To enter the simulation mode go to the copy mode and perform the following procedures.
[P] [*] [C] [*] [Main code] [START] [Sub code] [START]

But first reset the error H5-01 by entering 14(main code) then 1(sub code), you might be already fix the problem.

Good luck

    Sorry for my mistake, You're right, the sensors are POD2 and on POD3 ( exit section ). How about POD1, did you test it ? This sensor located in the fusing section, there's also a plastic actuator to test it. Be careful while handling this fusing section because it is hot.

    BTW, to return from simulation mode, simply press [CUSTOM SETTING]

    That's it, you found the primary culprit. Try clean the gap and re-soldering the sensor circuit board. Also try to swap the sensor with other that worked to confirm the trouble comes from this sensor not the mainboard. If it's confirmed that the sensor is the problem and if it can not be fixed then you should replace the sensor.

    BTW please rate my solution and thank you very much.

    Good luck.

    F1-15 means you have finisher lift motor operation abnormality, the causes could be motor lock, motor rpm abnormality, motor over current or finisher control PWB trouble. Check the motor with simulation 3 - 3.

    Unfortunately i don't have the part guide for the finisher unit, But usually it is a straight forward micro switch as you mentioned with 3 contacts, COMMON, NO and NC made by OMRON or KEYENCE. In case of emergency you can by pass this switch by swapping the wiring of NO and NC contact, but it is not recommended.

Error code U6-02

You have a large capacity double tray, the code is for the lift up motor in the right hand tray (that lifts the paper stack to the rollers) pull out the tray and see if there is paper wadded between the tray and the back wall of the machine blocking the motor boss from meshing with the tray.

Clear the motor error code with SIM 15 in the service area of the machine (from copy mode, # * C * to access)

If the code comes back your lift motor is worn out and needs to be replaced

Sharp AR-M450 is showing error code ''H4-00''

You're getting a heat roller low temp detection on the fuser in your copier. The fuser is the device that provides heat and pressure to the toner to bond/fuse it to the paper (it's that black, rectangular box in the upper part of the body when you open the left-hand side of the door).

Chances are a peice of paper is jammed up inside and blocking the sensor (probably a small peice that tore from a page someone tried to pull from the fuser). That or the temp sensor is defective.

Sharp AR-M350/M450 scan to desktop

Hi there,

Network scanner tool (or NST) comes bundled with the Sharpdesk application. It can be loaded as a standalone but it is bundled software. If you have dealer access to Sharp's website you could download the software from there.
If this is a client of yours you should be selling them another copy of the software as it is no fault of your own that they misplaced the CD plus its extra revenue.
I would love to help you otherwise, but this is copyrighted software.
