 Posted: Tue Apr 01, 2014 10:06 am Post subject: Ricoh 240 grainy printouts |
  |
|
| I have a Ricoh 240W that has suddenly started printing a gray grainy background on the printouts. It is very light but it is there. They are no longer pristine clean printouts. Does anybody have any suggestions as to what would cause this? I have changed out the charge, transfer wires and the developer. Is this caused by a weak drum? |

Your drum is probably end of life. What is the mileage on the machine?

| the meter is around 20148. Unless the meter has been reset I can't imagine that it has had too much usage on it. Is it possible to reset the counter when you sell the machine? |

| The drums on that model don't come close to the advertized life in clicks and that problem sounds exactly like the problem of a worn out drum. |

| We ended up replacing the drum and the defect went away. So I guess it was a weak, end of life drum. Thanks for all of your help. |

We stopped selling those machines because of this very issue... when I went to school on that model there were rumors that the drum life was ridiculously low and someone asked the instructor about it. He stated that was completely false and the drums should last about 100k... They don't , we found that they only last a max of about 2 years even if the machine is not used or about 40k... when I went back to ricoh about this they then told me the life expectancy of the drum was only about 40k or 1 year! and that they overestimated life in the beginning before enough testing was done...however this does not effect the price they are charging for replacements.
The ricoh 240... the only machine I have ever seen where the developer lasts over twice as long (90k) as the very expensive drum...
another trick I used to do with those was replace the cheap non coated corona wires with xerox gold plated wires and they would last 3-4 times longer before the zebra strip issues would arise from the failing wire. this was after the ricoh tech support told me the wires were not gold plated and that gold plated wires were too expensive and not used to keep the cost down... really, what did that save in the grand scheme of things? |
