have their own adapter that usually comes along with them from the manufacturer, using the adapter will ensure the safety of the than using any other adapter due to the current and voltage rating of the adapter which corresponds to the power board rating of the .
Common problems can be resolved easily such as , incompatible cartridge, and , etc. but the problem of a power board of a is not an easy one because it can render the useless if the model is an old one. Besides that, manufacturers do not make provision for the selling of the complete parts of in the market which is has made it difficult to repair some of its serious electronic problems.
The adapter of my friend recently got damaged while using it in a generator light, we thought it is a minor issue so he needed to drop it with a nearby electrician for repair, after some days the electrician succeeded in repairing the adapter and told him that it was some capacitors and resistors that got damaged due to the high voltage coming from the generator but he had changed all of them, the adapter was tested with the and it worked perfectly.
After settling him for the workmanship, we thought the case has been resolved but never knew that the action taken will be the starting point of the printer problems. The printer worked perfectly for months until one evening it was used with a public power supply and suddenly it turned itself off. When taken to a printer servicing office, it was confirmed that the power board of the printer has been burnt. The sad news is that; the printer power board is no longer sold in the market because it is an old model except one sees any condemned printer of the exact model so that the power board can be transferred to the , we had waited for months now without any sign of getting a new power board of the .
Based on the checking conducted on the , it was concretely found that the board got burnt due to the adapter that had been repaired with inaccurate capacitors & resistors ratings thereby creating room for excess current to flow into the power board of the and getting it burnt.
The experience has made me drop this post in a way to discourage repairing of the since it creates conditions that can make the power board to be condemned and potentially render the useless.
WHAT IS A POWER BOARD AND WHY IS IT IMPORTANT
The power board of a is the board that receives the current from the power supply and the same board has all the accessories attached to it for the processing of the functions and issued commands. It can be referred to as the heart of the because it is where the whole actions of the are processed before the main , , or can be carried out by the . If the power board of a gets damaged and its replacement cannot be found then the may become condemned.
