The maintenance price of Qianqiao Canon printer will be different due to factors such as fault type, maintenance difficulty and service area. In general, the maintenance cost of pure software faults will be lower, while the maintenance cost of hardware faults will be higher. The following is a rough price reference:

1. Printer cleaning and maintenance: 100-200 yuan/time, depending on printer model and service provider.

2. Replace parts such as gears and transmission belts: 200-500 yuan/time, depending on equipment failure.

3. Replace the nozzle, print head, etc. : 300- 1000 yuan/time, which also varies according to the equipment model and fault situation.

4. Replace the motherboard such as the drive board and power supply: 500-2,000 yuan/time, and the maintenance cost should be judged according to the specific situation.

5. When the main parts of the printer need to be replaced due to extensive damage, or the whole machine needs to be replaced due to major failure, the cost is also very high, even exceeding the price of new equipment.

The best way is to prevent maintenance in advance, clean and check the printer regularly to avoid excessive wear and tear of the equipment, and also reduce the maintenance cost. Choose regular maintenance points and service providers, avoid choosing some irregular or unlicensed maintenance points, and avoid new failures caused by improper maintenance.
