Canon Ink-jet Print Failure Analysis and Repair
The following are some common faults and maintenance methods for Canon ink-jet printer: ** 1. Power supply failure ** 1. ** Failure symptoms and analysis ** - If the indicator light on the panel did not show up after turning it on, the fault might be in the power supply part of the printer. First, he understood the working principle of the power supply. The 220V alternating current was filtered, rectified, and smoothed to obtain about 300V direct current. After a series of circuit components, the power supply formed an oscillation. The sample voltage of the power supply was 28V. When the main voltage rose, it would be stabilized through the internal circuit. When the panel indicator light did not show after the power was turned on, it might be that the work process was not carried out. 2. ** Repair Case ** - For example, if the casing was opened and there was no +28V or +5V output, the fuse F1(2A/250) would be blown. In this case, it is necessary to further measure whether the filter capacity, the thermometer R1, and the bridge stack (RC1) are normal. If these components are normal, it may be that Q1 (the crystal) is damaged. If it is found that the c-e pole has been broken down and short-circuited, and if R6 is over-current and burned, ZD2 is broken down and short-circuited, the printer may return to normal by replacing F1, Q1, R6, and ZD2. ** 2. Print head related faults ** 1. ** Failure symptoms and analysis ** - Canon Canon BJ - 330 ink-jet printer's print head moved during self-test, but it couldn't print any characters. This situation might be related to the delivery tube connecting the ink box and the print head. If the casing was dismantled, the ink in the plastic delivery pipe connecting the ink box and the print head was intermittent. Normally, it should be filled with ink. During the power-on self-test, the ink in the pipe moved slightly but did not move for a while, which may be the negative pressure generated by the print head. 2. ** Repair Case ** - In response to the above situation, you can use tweezers to lift up the tube. If the ink movement in the tube is significantly faster, when the ink reaches the head of the printer, the character will be printed, which means that the transmission tube is not connected properly. At this time, after connecting the transmission pipeline, the printer could resume normal operation. ** 3. The indicator light is not on, and there is a fault ** 1. ** Failure symptoms and analysis ** - Canon Canon BJ - 330 ink-jet printer did not light up after it was turned on, and the printer did not respond. This meant that the power supply of the printer was faulty. The power supply of the ink-jet printer was a separate circuit board, which was used to convert the city power into the +5V and +28V voltage required by the printer. There were a total of six wires for the power supply output. Different color lines corresponded to different voltage. If the voltage of these circuits was abnormal during the measurement, it was usually the power circuit itself that was faulty. Read more exciting novels for free

Canon ink-jet printer becomes slower after changing to a computer
The slower speed of the printer after changing to a computer might be because the printer had enabled "spooling" when printing. You can determine this by right-clicking the printer in the program on the left side of the computer, or by opening it in the control panel, right-clicking [Printer-Attributes], selecting the [Sharing] option in the "Attributes" dialog box, ensuring that the printer is in the shared state, and then selecting the [Advanced] option to check whether the [Print in the background so that the program can print quickly] radio button is selected. If it is selected, it means that "Spooling Print" is enabled. It could also be a problem with the USB interface or a problem with the processing of print attributes, such as sending it directly to the printer or sending it to the printer after processing. You could try to re-install the driver or reset the system. The machine itself may also have problems. Some machines can adjust the printing speed directly on the machine. In addition, there might be a situation where the driver could not be recognized due to insufficient power supply. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
