The A4-sized monochrome inkjet printers achieve their compact size with an ink tank placed at the front side. In this way, it takes only one glimpse to check the ink level in the tank. If a refill is required, the ink bottle is inserted into the printer, and the missing ink is automatically refilled. The printers allow for productive work, as the ink is sufficient for the printing of 5,000 pages. In comparison with models using printer cartridges, refills are required much less frequently.
