I am helping a non-profit that has an oversees office. The office has a MX-620N used for printing training materials. They can get supplies in their area, however the local tech support is very poor.
Recently they had light prints and so tech came and replace the drum and the same problem. Then replace the toner cartridge, same problem. Then they thought the toner was bad so replaced the developer. During this time we kept getting FS-02 error code. Replacing the toner cartridge fixed this, but still light prints. However after replacing the developer we got a F2-00 code. After checking it the tech used two bags of AR-450ND ( for a total of 900g.) After checking the manual it is supposed to have used AR-620ND (two 750g bags for 1500g).
I assume first that even if the AR-450ND and AR-620ND are the same material that he would have needed to use the same weight.
My next question is are they compatible if the same weight is used?
