I have Epson Color laser printer CX11NF. It's developer toners run out and I need to purchase developer toners. But the whole colors of Epson products are more than 500.00 USD. I have to find compatible and cheap. Please guid me.

Oh, okay, I see what that thing is now... Technically its called a "developer roller" or "toner developer roller". It basically transfers the toner from the toner bin to the photoconductor drum.

Wow, most laser printers have that thing as either part of the photoconductor drum assembly (single-pass printers), or at least part of the toner cartridge (multi-pass printers). Looks like Epson found another way to overcharge people for yet another consumable.

As far as I can tell (after doing an extensive google search), that part is made ONLY by Epson. Although they look A LOT like the ones in Konica-Minolta printers (must use the same print engine design). Try looking on google shopping search for the exact part number(s) you need. You might find it cheaper than buying it directly from Epson.

I would recommend getting a laser printer that doesn't have this kind of flawed design. When researching for a new laser printer, look at the cost of ALL consumables, not just the toner. Consumables (things that either get empty, or eventually wear out) usually consist of toners, photodrum(s), transfer belt, and fuser (and for your printer, 4 "toner developers"). Look for a printer or printer brand that tends to have a lot of "after market" (aka clone/compatible) consumables, or consumable reset chips/devices.

An older "used" refurbished printer can sometimes be the best deal out there (get at least a 30 warranty though), because there are usually after market consumables, especially for business/work-group class printers (your best bet if you do a lot of printing). For example, my P3005N B&W HP printer (refurbished), with extra tray (can hold 2 reams of paper) only cost me about $160, with a full high yield toner (about $200 if you include the $39 cost of getting HP tech support for a year). My Samsung CLP-510 color laser printer is slow, has some driver problems, but it only cost me $69, all 4 color toner refills are only $119 with reset chips, and the expensive consumables don't have end of life chip in them. It was so cheap I bought two of them, just for the expensive consumables. Printers that haven't been out for very long probably won't even have after market toners available for at least a year.

Unfortunately many laser printer Mfg's have gotten wise to the toner after market biz, so they design their much harder to copy parts (like your toner developer drum, fuser, & transfer unit) to stop working after X number of prints, even if it is perfectly fine. Another trick they do is to redesign their printers slightly (same print engine technology, same toner, just different size now) every few years, which keeps the after market companies from making the expensive consumables (like fusers) because there are only a few hundred thousand of those printers out there, and most of those people get their consumables from the Mfg or just get a new printer... Printer companies don't sell printers, they sell consumables.

Unfortunately, most printer companies design their products to be cheaper to throw away than to fix.
