HP Photosmart D110a Troubleshooting
Printer will not turn on
Unexpectedly, the printer might not turn on.
Over time components on a motherboard will eventually fail, which can prevent the printer from turning on. Many complicated reasons can be responsible for components failing, but a simple fix is to replace the entire motherboard.
Power button failure
The button itself may malfunction due to broken plastic behind the button. This can be a result of plastic cracking or breaking. A loss of contact between the button and the hardware prevents the printer from turning on. Replacing the power button will restore contact.
Printer will not print
The printer does not perform.
Improperly installed cartridges
For the printer to function properly, the devices need to have their interfaces touching with the printer's PCB(Printed Circuit Board, the green board that makes contact with the cartridges). If the cartridges are installed incorrectly, there is no communication made between the printer and the cartridges. Consequently, the printer will not perform. Reinstalling the cartridges such that the interfaces contact the PCB alleviates this.
Printer paper can become stuck during printing. Mangled or stuck paper is often caused by the printer taking in more than one sheet at a time. Unjamming the paper allows the printer to continue functioning properly.
Color cartridges will eventually run out of ink. Usually the computer will acknowledge when the ink cartridges are running low. Solving this issue is as easy as replacing the cartridges.
Printing is flawed
Printed images might have poor quality.
Low ink levels
Low ink levels affect the image and color quality negatively. Replacing the ink cartridges can resolve this problem.
Display cannot be read
The LCD screen can malfunction and become unreadable.
Damage to the LCD can result from improper handling of the printer. LCD screens are fragile and are subject to damage very easily. If damaged, the most practical solution is to replace the LCD altogether.
The actual LCD module can become damaged and no longer fuction. The LCD screen can become hard to read due to damaged pixels, faded saturation, and bad contrast. Bad or broken internal LCD components are the major contribution to LCD failure. Replacing the LCD screen can restore clarity to the interface.
Scanner does not function properly
A faulty scanner prevents images from being scanned.
Over time, the scanner can become misaligned from general use or mishandling/moving the printer. A misaligned scanner can cause the scanned images to be crooked or offset. Realigning the scanner will allow the printer to once again properly scan documents and pictures.
Defective scanner glass
The scanner glass is important for protecting the scanner and providing a flat, transparent surface for documents to be scanned. If damaged or compromised, the glass must be replaced for continued scanning.
