Samsung Scx 4521f - Copy Count Help

[Guest]

I have purchased about 15 Samsung SCX 4521F multifunctions for suppy to various customers. The start-up cartridge is supposed to make about 1000 copies and then call for toner. The next cartridge should make 3000 copies before calling for toner. 4 of these machines have called for toner after 500 copies (start-up cartridge) and after about 1500 copies (follow-up catridge) I have taken the first two back to the suppliers representitives and after 3 weeks had some "board" replaced under warranty. As this MFP does not measure the toner, but counts the copies this creates a mega problem from my customers who land up with half full cartridges. Any solutions, as I can not afford 3 weeks and a lot of carry in expenses to have the problem sorted out when noticed 500 copies later (usually by the customer) and I cannot make 500 copies every time before supplying to the customers! Please Help!!!

I had same type of problem with the scx 5530. Couldn't get any solutions from Samsung so I chose the ignore toner empty option (which makes the toner light not come on) and told the customer that when copy starts to get light change the toner. It has worked well toner lasting much longer.
