Different Technical Characteristics And Printer Repair
Let's first compare characteristics of various models of printers. In order to make qualitative printer repair, pay attention to the following characteristics.
The sanction is maximal number of dots per inch, which the printer can print. The quality of a press is higher when the sanction is higher. However keep in mind, that manufacturers in the description of the models usually specify the maximal sanction, i.e. the sanction that can be received, using at a press special programs of optimisation. Recommended sanctions are: for a press of the text it is enough 300 dpi, for a press the schedules - 600 dpi, for qualitative press of photos - 1200 dpi.
Speed of a press shows, how many pages the printer prints for a minute. Speed of a black-and-white press is usual a little bit higher, than of colour press. There is also a small cunning: in the description of models usually the maximal speed of a press is underlined, i.e. the press of the text at the poor quality (which is adjusted by adjustments of the printer).
Processor and memory size - the more is memory size and the more quickly the processor is, the more quickly document is printed (especially the difference is appreciable at a press of a "long" file, as for example, a colour photo with a greater sanction).
Interface of connection characterizes a way of connection of the printer to the computer. Earlier printers were connected to standard ports LPT or COM. Now practically all printers have an opportunity of connection to USB-port. The majority of new printers support such interfaces as infrared port, Bluetooth and even Wi-Fi.
Refuelling of the cartridges is a procedure simple and fast only at first sight. It is not recommended to entrust it to the not skilled person. It is necessary to understand in perfection the different models of printers; the know how to open the case and to remove the cartridges, correctly to pack them for transportation. It is necessary equally well to carry out both refuelling of colour laser printers, and refuelling of jet cartridges. Non-observance of these subtleties leads to the damage of printer and to its expensive repair.
