Ricoh MP C307 Not Printing, Scan Not Working & Paper Jam Errors

The Ricoh MP C307 tends to fail in partial, misleading ways. It may still power on and still look available on the network, yet stop printing from one workstation. It may still show a USB stick on the panel, yet refuse to scan to it or print from it. It may accept a new toner bottle, show normal status for a moment, and then immediately return to a toner-empty or waste toner message. 

It may also throw repeated feeder or scanner-side startup errors that look electronic until the real obstruction or scanner carriage problem is found. Those are the kinds of MP C307 failures that keep getting misread as broad driver, offline, or Windows 11 issues when the real fix is much narrower.

Problem: The MP C307 kept dropping out and would not print reliably from one location

What users observed: In one reported MP C307 case, the machine developed intermittent not printing behavior for one specific workstation. Jobs would fail with messages such as the printer not responding or the remote host not accepting the data file, and the problem often appeared after the user left and returned to the office. Reinstalling the print path would make the copier work again for a week or two, which made the problem look like a software issue at first.

What was tried: The printer firmware was updated, the print system on the computer was reset, old Ricoh files were removed, operating-system updates were checked, and the printer driver was reinstalled. Users also rebooted the copier because queued jobs sometimes released after the reboot.

How this played out: In the solved report, the problem was not the MP C307 itself. The real fix was replacing a bad network switch at that location. Once the switch was replaced, the same intermittent not printing pattern stopped, which is exactly why this case matters: the copier kept getting blamed for a network fault that followed the location rather than the machine.

Problem: The copier could see a USB memory device, but still would not print from it or scan to it

What users observed: The MP C307 recognized that a USB stick had been inserted and even showed the memory icon on the panel, but when users pressed it they got a cannot access the memory storage device message. In the same environment, the SD card slot still worked, which made the USB path look selectively broken rather than fully disabled.

What was tried: Users checked whether the USB and memory-device functions were active in settings, reformatted the same flash drive, and tested that same drive on another Ricoh machine where it worked normally. They also kept retrying the same USB stick because the MP C307 was at least seeing that something had been plugged in.

How this played out: Two real fixes surfaced in that same case. First, the workflow had to be followed in the right order: users had success only after going into Store to Memory Device before inserting the USB stick and waiting for the device to become ready. Second, the original stick itself turned out to be the problem in the solved report, because switching to a different flash drive brand made the function work immediately. On this model, that means a visible USB icon does not guarantee that the stick is actually usable for scan-to-device or direct print.

Problem: The copier kept saying cyan toner was empty even after a new bottle was installed

What users observed: Users reported that the MP C307 would show a lack of cyan toner even after a new bottle had already been installed. In one case, the copier also showed the waste-toner bottle as full even after it had been emptied, which made the whole toner path look unstable rather than simply low. In another report, the copier recognized a new cyan bottle, printed a few color pages, and then dropped straight back into an empty-toner state.

What was tried: Users changed the cyan bottle, emptied the waste-toner bottle, checked that the toner was the correct type, and reseated the bottle. In the repeated cyan-empty report, the toner bottle was also swapped again and the cartridge contacts were cleaned, because the toner state kept returning after only a few pages.

How this played out: In the solved MP C307 case, the cyan-toner message cleared only after the bottle was repositioned several times until the machine accepted it correctly, and the waste-toner-full state cleared only after a manual reset of that waste-toner status. In another reported cyan-empty case, the real fix was unblocking the toner pump passage and then installing a new cartridge again. On this model, a toner-empty message after a fresh bottle does not always mean “bad toner.” Sometimes the bottle is not seated correctly enough, and sometimes the toner-delivery path itself is blocked.

Problem: The settings were locked, the admin accounts were blocked, and normal reset options did not help

What users observed: A used MP C307 coming from a managed environment could still be reachable by IP address, but the admin and supervisor accounts were blocked and the expected factory-reset path in ordinary service mode was not available. That left users with a copier that was physically fine yet practically locked out of its own settings.

What was tried: Users tried the usual service-mode path first, looked for the expected reset option, and even investigated NVRAM-editing approaches because the normal reset flow was not working. Those attempts did not help because they were still being done from the wrong level of service access.

How this played out: The working answer was not in normal service mode. The reported fix path required Factory SP mode, and where that route still could not restore a usable state, the fallback answer given in the same discussion was a replacement NVRAM. This is why “locked settings” on the MP C307 is not the same as a simple forgotten password. The machine can reach a protected state where the ordinary reset path is no longer the one that matters.

Problem: The scanner or copier startup failed with an SC121-type error

What users observed: In one MP C307 service-code case, the machine developed an SC121-type startup problem tied to the scanner side. That kind of fault can make the copier look like it has a major electrical or board issue because it blocks scanning or copying right at startup.

What was tried: Users had already gone through the usual resets and were still facing the same startup problem, which is why attention shifted away from ordinary restart behavior and back to the scanner path itself.

How this played out: In the reported solved case, the real cause was a stuck lamp trolley that prevented a proper white-reference reading during startup. Once that scanner carriage issue was corrected, the copier stopped behaving like a dead scanner not booting case and returned to normal. On this model, that matters because not every scanner-side service code is an electronics failure — sometimes the scanner carriage itself is physically stuck.

Problem: The document feeder kept throwing phantom jam codes even though no real jam was visible

What users observed: Another MP C307-family issue showed up as repeated feeder or original-side jam codes such as J001, J045, or J054, sometimes at power-on or when a cover was closed. That kind of feeder behavior makes the copier look like it has a chronic paper jam problem even when users cannot see any page stuck in the feeder.

What was tried: Users looked at the jam codes themselves first and compared whether the fault followed feeder use, power-up, or cover movement. Because the error kept coming back without a visible full-size jam, the troubleshooting moved from paper removal to sensor-area inspection.

How this played out: The actual fix was finding and removing a small scrap of paper or other foreign material near the registration sensor. Once that obstruction was cleared, the repeated phantom jam behavior stopped. On the MP C307, that is an important distinction: a feeder jam code does not always mean a full page is still trapped inside. A small leftover scrap in the sensor area can keep the copier in the same paper jam state all by itself.
