The developer goes into the developer unit. It is a supply that your tech installs. The copier you have needs both developer and toner. The developer is iron fillings that are used to hold the toner on the mag roller of the developer unit. It gets worn out over time. Good Luck
quote is probably in the right price range. you need to look at how many copies are on your machine. look at any future repairs/supplies that will be needed. like drum, developer unit. If these are also needing to be changed soon, you will have to plan on those costs also. Any comparable machine that you get get will be expensive to repair the big items. You have to put all of the money that you spent on the machine and find out how many copies you have made. you can then figure out the cost per copy. At the same time, if this machine does everything that you need from a copier, do you want to buy a new one at much higher cost.
after replace developer you dont turn round the developer wheel left side. only right side.try this take out the developer and after re fill in to the developer unit. and u change the main charger unit also.

The developer you need to purchase is 1620 , and the drum unit also the 1620, you can see this number in the toner catridge itself. or in the toner catridge box. Regd. the 161 you need to purchase the products name 1620 number and the concerned part like developer, drum, toner, some gears etc.
