EPL-6600 /ActionLaser 161W Service Menual Opwatig Princ@ee 2.1.1.1 Paper Feeding There are two methods of feeding the paper into the printer. One is by using the multi-purpose tray (standard tray), and the other is by using the optional 25kheet lower paper cassette. Paper~ut conditions are detected by the paper empty sensor, located above the paper tray or the cassette. While paper is in the tray or cassette, the detection lever for the paper empty sensor is lifted.

The engine starts printing when the detection signal is received. 2. To detect paper size. The printer detects the time it takes for paper to pass the paper take-up sensor during paper feeding. If this time is lon& longer paper is feeding; if the time is short, shorter paper is feeding. 3.

EPL-6600/ActionLaser 1600 6ervice Manual Operating Principles Print data and commands transmitted from the host computer via parallel, serial, or optional interfaces are read using the interrupt process of the CPU and stored in the DIUM input buffer. Data and commands in the input buffer are processed by the CPU, which then stores the printing bitmap data (image data) in the V (video) -RAM (image buffer) in the DRAM. The size of the V-RAM depends on the available DRAM size.

Maintenance EPL-5600/ActionLaser 1600 Service Manual 6.1.1.2 Consumable Replacement This printer uses consumable imaging cartridge SO51O16. The life of this cartridge is 6000 pages when printing on A4 or letter size pages with a 57. print ratio. If printed images become faint, remove the cartridge and gently shake it. This will distribute the toner and may make the images darker. If the image is still too light, replace the imaging cartridge.
