Question: I know the manual says you can clear User Access
Codes in Service Program 7810 but it does not appear. And the manual
does not mention a second level of service programs. Any one have an
idea? Thanks.
Answer: Most likely you need to be in Special Service Mode.
Hold down the # key while selecting copy SP, then enter the SP you
named above; it should show up.
Question: Been there, done that. It still won’t let you
access SP 7810.
Answer: You can try inputting 5832 6 HDD Formatting (User
Info), but make sure to note all the user settings
Answer: They don’t have a key op code - restricting access to
the user tools is done with administrator authentication management.
Question: Sorry for calling them Key Op Codes. The customer
forgot the User Access code. I have no access to change
authentication tools. Whatever you wish to call the code it needs to
be cleared and I cannot access SP 7810. Thanks.
Answer: If the supervisor login does not work (that is, the
machine pre-dates this ability), you can only reset it by replacing
the NVRAM. Login with username=supervisor, and leave the password
blank.
Answer: I know this may be a stupid idea, but it got me out
of trouble with a Ricoh 2060 NVRAM. I had bought the machine from a
wholesaler, and when my IT guy came in to set up the print/scan
network, he could not get in because of an unknown password, so I
ordered the new $250.00 NVRAM. Installed it and then tried to reload
the machine from my memory chip. However it carried the unknown
password with it, so I was no further than before. Out of
desperation, as I knew I would have to buy a 2nd NVRAM chip and wait
2 weeks to get one, I took aluminum foil and shorted all the pins
together on the NVRAM chip as I held it in my hand. Amazingly it
reset to default, which then allowed us to program our own codes and
get on with the installation. I don’t know if it could work again,
but it did once. Good luck.
Question: Thanks everyone for all your help and ideas.
Answer: Check the mag roll for dev on the end where background occurs. There may not be any (dev) because the machine may have not been level and leaking dev. Clean top and bottom of lens, and replace blade. Reverse the drum if it is still there to see if the problem follows it.
Question: If there is no dev at one end, wouldn’t that result in no image on that particular end? It doesn’t look like a drum fault to me, as there isn’t a smudge as if it has not been cleaned. I’m wondering if it is the erase lamps blown on one end. Also, I cannot find any mag roller bushings to prevent the dev leakage. I am having the client check the machine is level as we speak. Any other ideas?
Answer: You may not get an image because the toner “cloud” will transfer toner to higher potential, which is the drum, but there is no developer to “wash” the background area that is at the lower potential. The effect is the same as if it were over toned, except there is no developer brush (or just maybe a very skimpy amount of developer) that would develop the image better. Where there is no dev, that area may eventually have a ton of toner collecting there depending on the dispensing system. The copy does take some of the toner away, but not enough; the image, if there is one, is light, but there will usually be background.
Question: I am planning on replacing the erase lamp assy and dev. The background has now gone from 2-3 inches to a 1/4 of the page! Before I replace the erase lamp, I need to know one thing: the tag chart states there is no Tag model 30 and I know there is a difference in the erase lamp on a pre Tag 30 machine to a machine with Tag 30. Can anyone tell me if there is a physical difference? In the manual it says to check the erase lamp on a pre Tag 30 or check the erase LED’s on a Tag 30. I’m guessing on the pre Tag 30 the erase assembly uses a lamp and on a Tag 30 machine it uses LED’s? Can anyone tell me? Also, the copier is now stating the toner is low but it is brand new! The copier is not even in use due to the fault!
Answer: I didn’t know there was an erase lamp. LED’s are all I know of. I think you can sight down the lamp when it is lit from the side doors. The toner tube has to turn; it may not be in all the way. I’m not sure why there is toner on a small portion of the drum. Is the blade scraping it off or is the toner bypassing the blade? If it’s cleaning, check the selfolk lens (clean it), and the lamp. Check the erase section to see if it is on.
