Question: Jam light stays on. Spring loaded fuser door and flag is good. Blew out sensors. Optics rail clean, no hesitation. What else should I check? Answer: Don’t know if it holds true on the 1631, but the constant light was a burnt fuser bulb. Might be different these days. Question: Nope. Fuser lamp comes on. Then jam light. Answer: Check paper in sensor under the drum unit at ps rollers. Have you seen if the past toner dust gets on this sensor? Try air to this sensor. Also go to test command 30 and check each sensor. Answer: I have had, more times than not, this problem turn out to be a jam sensor on the bottom of the machine. You have to remove the toner and drum carts and lay the machine on its right side to get to it. It’s been awhile but I believe the little panel that holds it is just above the pick-up rollers. Be advised that there is a mylar piece glued to the machine that you will have to re-stick. I would take some contact cement with me. Good Luck. Answer: Go with service code 30 to see each sensor work. Answer: Will the fuser turn on if a sensor is blocked? Don’t think so. Are you going into an overheat? Question: Got it! Sensor at fuser! |

Question: When print problems occur and you need to
test the network card, you can connect a laptop to this
printer. But, how do I make the connection? Is it via router
or directly to the printer? Should I install the drivers for a
local printer? Thank you in advance for your answer. Answer: Not a Ricoh guy, but yes. Depending on your equipment. Generally speaking a cross-over cable can be used to connect directly. Most newer laptops will do the crossover themselves if a standard cable is used. But using a switch of some sort is usually more reliable. The print drivers would need to be installed. Question: I see the light now. Answer: Unless you are trying to test a particular function you can use a generic print driver that is installed in nearly every version of Windows. You can also look under HP and and try a standard HP Laserjet 5 driver. I’ve noticed that Windows 7 no longer has this driver as standard. Answer: Yes, you can. If you download a Ricoh driver that is a PCL5, it should work on about everything Ricoh. Print out a config page and set the laptop’s IP address to one or two different than the copier in the last octet. Answer: I connect my laptop direct and manually configure the IP address on the laptop, generally one octet higher than the printer/mfc. Then I use HP driver or universal print driver and configure the port to the IP address of the printer. Now test print. Question: Many thanks for your answers; I’ll try it out today. Have a nice weekend!! |

Question: We have a customer with a Toshiba E350 and
a MJ1023. The machine jams every 25-40 prints/copies. The
error shows it to be in the exit. Another tech has already
changed the sensors in the sorter. In an earlier post it was
reported that the Bridge switch/sensor could be sticking due
to the heat from the fixing unit. Has anyone been successful
just cleaning the switch or is it best to replace it? Does
anyone have the part number available, if it has to be
replaced? Thank you in advance!!! Answer: We clean them all the time. It should work. Answer: Did you check your error history? If you’re getting multiple E920, E930 0r E940 errors, then this points to the bridge sensors causing the problem. Don’t waste your time trying to clean them. Just replace them both. The part number is the same for both. PN# 41321248000 photo interrupter. Answer: If the jams are just nice neat jams, meaning the machine just seems to stop then the s/t unit or main could also be on its last legs. I’ve cleaned bridge sensors but had to finally replace them. You may have to sit there and press the print key 50-60 times to send one piece of paper through each time to determine exactly where the jam is occurring. Answer: While you have the bridge unit out, exchange the spring from the bin full sensor to the first bridge sensor. Question: Thank you for the input. It sounds like I better order the switch and sensor before heading out. After all, it now costs over $35 in gas alone to get to this account. Answer: While you are there, take a look at the exit sensor’s actuator in the fuser. The old style actuator bubbles out from heat and if it bubbles out big enough it will hang-up intermittently causing exit jams. You’ll know what I’m talking about when you look at it. It almost looks like it is made with a bulge in it, but you can take a file and file it flat on both sides again and it will work. |

Question:
Touchscreen is out of alignment. I can get
into service mode but it’s not allowing me to select the
appropriate tab on top because it’s out of alignment, so I
can’t even get into FUNCTION/TOUCHCHECK adjustment. Any help
on this would be great. Thanks! Answer: I had the same problem, and was able to get it to adjust by unplugging the control panel. Had to do this twice and finally it would not respond to any touch. Found out these control panels go bad often. Hytec offers repairs for about $375. Sorry for the bad news. Hopefully, you can get it to reset a couple of times. Question: Thanks so much for the feedback. Just what I thought. Thanks again! |
