What is the development unit made of?
The development unit is made up of thousands of small magnetic beads attached to a roller - a rotating cylinder made of metal. The beads carry an electric charge and attract the toner powder with opposite charge.
What does the development unit do?
The development unit plays an important role in getting the toner to the page. The development unit (also called a developer unit) attracts toner powder from the toner hopper. It then rotates and passes on the toner (that is coated on the beads) over to the drum unit, which has the electrostatic image written on it by the laser. The stronger charge on the photosensitive drum draws the toner away from the development unit and on to the image (to be printed).
Development units in a colour printer
Colour laser printers have four instead of one toner cartridges (cyan, magenta, yellow and black) and have separate developer drums for each toner cartridge. If you are buying a replacement developer unit for a colour unit, you need to usually buy and replace for the exact colour based on what the display screen error message mentions.
When is it time to change a developer unit?
Look out for these signs that might indicate that your printer’s developer unit needs to be replaced:
- Error message on display screen asking for replacement of development unit (also called developing or developer unit).
- Lighter prints, even after recently replacing a toner cartridge
Refer to your printer's instruction manual or check your brand and model number online for instructions as to how to replace your developer unit.

ALWAYS HAPPY WITH THE TIMELY SERVICE FROM INK DEPOT
Amazing amazing service!! Really needed my maintained box ASAP for my printer and they did not disappoint. Same day shipping next day delivery. Thanks!
I have found InkDepot to be very reliable and are as good a price as anyone, I use them all of the time. Delivery is fast, my last order was delivered on the same day of order. There was an error (one ink was the wrong colour, which they noticed before I did!), they notified me of the error and sent the correct one immediately which arrived the next day (the time that this has happened to me after many 10's of orders). I've found Ink Depot to to be very fast with delivery, very reliable and when a rare error occurred, the identified it, corrected it immediately with no issue for me.

The Epson Compatible ink refills have proven reliable in terms of the refill procedure and the stability of the ink remaining in the bottle until the next refill. There is no spillage from the bottle tip when the plastic membrane is pierced when the bottle is upended at the printer's filling point and the screw cap prevents any drying out of the tip. The colours are true to their description.
General FAQ
An Epson EcoTank printer is designed for businesses that print large volumes regularly and would like to print on for months before there is a need for ink bottle replacement. An Epson Expression printer is the right choice for homes and small businesses and is very compact and offers lots of useful features while Epson WorkForce and WorkForce Pro series models are great additions in medium and large businesses as they offer fast print speeds, multifunction capability and an intuitive user interface.
Epson EcoTank printers could potentially print for years on a single ink tank. There are individual ink bottles for each colour, so you need to replace only the colour that is exhausted. This reduces wastage and proves to be cost-effective in terms of operation costs.
