ABSTRACT Most often, the printing of very important reports have been stopped midway owing to some minor faults on the computer/printer system. At times, due to the complexity of the faults some maintenance personnel find it difficult beginning to perform detailed diagnosis due to lack of specialized equipment, some of which are available only to a few big firms due to their high cost of acquisition. As the case may be, some of those faults may be such that will require a very fundamental knowledge of printer maintenance, making use of minor tools. Once the actual causes are identified. This project “EPERT SYSTEM ON TROUBLE – SHOOTING AND MAINTENANCE OF EPSON PRINTER” looks at trouble shooting and maintenance information for non-computer/printer engineers..
