Lanier LD425c toner not loading

Check on mfg site for reset procedure on printer.

after refill the toner may be bias charging roler is not proper fiting
or toner cartridge is not proper insert

Try removing the toner cartridge and gently cleaning the electrical contacts for the sensor. Sometimes they get toner residue on them and give false readings.

the best thing to do is buy the original toner. how ever if u really can't then try changing the blue colored one

The toner cartridge maybe failed, try with another cartridge.

Replace the toner holder/hopper part # B082 3209 -Carl

Make sure you have the plastic seal on the toner bottle. The seal prevents toner from spilling inside the machine.

It could be that the black developer unit is clogged. The toner low sensor is located in the black developer unit. A trained copier tech may be needed to troubleshoot this.

Try taking out the cartridge and reinstalling it. Was this a original ricoh toner cartridge or a el cheapo cartridge off the internet?

I had the same problem and found that one of the toner cartridges must have not been seated properly. I removed the black toner cartridge and re-fitted it. The printer now works fine again with no errors. 17H is a code relating to a fault in the rotation ......... possibly one or more toner cartridges need checking. Use the menu on the printer to turn it to the appropriate position (i.e. engine menu then select replacement of whichever toner you are checking).
Hope this fixes your as well.
