A, hp printer common 3 fault solution
1, printing shows encounter DOT400X port error, this situation is mostly due to the USB port problems, either not recognized correctly, or the length of the USB cable does not meet the specifications.
Solution: replace the USB cable, there is also a possibility that the printer's driver does not realize the correct installation.
Even if the installation is correct, the driver does not match the port. Therefore, when we troubleshoot, we should combine these three to analyze the cause.
2, the printer's USB port to the computer's another USB port, the computer shows "auto-installation", but does not show the icon, trying to use the original computer driver to print no response. Such a problem, then we should seriously doubt whether only a USB port, and another USB port is not installed successfully. At this time we enter the original driver, find "Properties", and then click the port, the printer shows "offline status" unchecked, then restart the printer to print, there should be no relevant failures.
3, run hp comes with the CD-ROM installation program, if in the copy file at the end of the last error window, or "add a printer" way to end the installation, the interface displays "can not find the specified file" and other errors.
These problems are often caused by the fact that after installing a program over and over again, the program itself appears to be in an unusually disorganized state on the system. To solve this kind of problem, we should use the original driver premise, use the "Device Manager" to "other devices" unchecked, and then refresh the system or scan for new hardware "USB Printing Support". "thus get updated. Here I suggest that you in the "Drivers" directory in the "HB" directory click, the system will automatically find the corresponding file, eliminating the need for a lot of trouble later.
Second, hp printer can not print normally
1, fault phenomenon
hp printer power on, the word car to the left to move a certain distance after stopping, the printer on the right side of the suction mechanism to rotate for a few times after stopping, the operation panel [paper] indicator light flashes, the printer does not print.
2, fault check
Normal conditions, hp printer power on, the printer on the right side of the suction nozzle cap down, away from the inkjet head, then the word car began to move to the left, to be moved to the left end of the rapid return to the right side of the suction mechanism (inkjet head cleaner unit) at the suction mechanism began to carry out the cleaning process, including wiping the nozzle and suction of two operations of the inkjet head. When cleaning is completed, the nozzle cap of the ink suction mechanism moves upward to cover the ink jet head. Waiting for the execution of the next print command. This fault is the printer as soon as the printer is turned on its word car to move to the left, and the ink suction mechanism is constantly rotating, indicating that its ink suction mechanism of the nozzle cap in the power before the inkjet head is not covered.
3, fault analysis
According to this analysis may be the suction mechanism in the transmission mechanism is faulty, so that it can not be normal reset; suction mechanism in the position detection sensor failure, that is, the suction mechanism can not detect the inkjet head, the report of the error message.
4, troubleshooting
First, unplug the power supply, use a screwdriver to pry open the four slots from the back of the printer from the snap (left and right each two), remove the rear cover. Unplug the operation switch on the bottom cover from the main control circuit board, use a one-word screwdriver to pry open the snaps on both sides from underneath the printer's face cover, and lift up from the front to remove the bottom cover.
Use a special tool to unscrew the five screws under the printer frame and remove the black plastic bottom plate. Move the word carriage to the center, unscrew one ink suction mechanism fixing screw located on the right side of the frame and two screws at the back of the frame from the front of the printer frame, unplug the position sensor of the ink suction mechanism from the main control circuit board, and then remove the whole ink suction mechanism in the direction of the frame.
With the multimeter RXl block check the ink-suction mechanism sensor (the sensor is a normally open reed type), that is, the pen inserted in the sensor plug, hand-rotated ink-suction mechanism of the drive gear, observe the nozzle cap rises to the highest point of the multimeter on the needle there is no reaction to determine whether the sensor is not working. This case was inspected and determined that the sensor failure, replacement troubleshooting.
