Not only the horizontal tandem-type color laser printer but also a monochrome laser printer suffers from the same problem when a developing agent storage chamber is located above a developing chamber.
Since the problem of deterioration of a developing agent is caused by subjecting the developing agent to sliding friction, the problem commonly can occur over developing devices in which a developing agent is charged through friction charging. In the event that the developing agent is deteriorated, phenomena such as a reduction in fluidity due to the embedment of externally added agents which are externally added to the developing agent and a reduction in charging quantity due to a reduction in charging function are generated. This phenomena may cause rough and scattered printing and in worst case, background fogging, on an image formed on a recording sheet.
When a fresh and non-deteriorated developing agent is added to the deteriorated developing agent whose charging function is reduced, a charging failure is caused in the deteriorated developing agent depending upon conditions, and this may cause a situation in which the background fogging is worsened. Factory (or factory line) programming low-power devices such as wearables, medical devices, and the like, requires bidirectional communication between the programming device and the low-power device(s) being programmed. The low-power devices typically have a built-in radio frequency (RF) radio for transferring data. For example, many low-power devices in the healthcare, fitness, security, and medical industries utilize Bluetooth low energy (BLE or Bluetooth Smart) radios to transfer data. Many of these devices such as, for example, medical devices, have non-replaceable batteries with limited lifetime capacity. Prior to deployment of these devices, but before and after factory programming, it is often desirable to disable the RF radio, e.g., put the device in a sleep mode, to avoid current leakage which can significantly lower the shelf life of the device.
There are various mechanisms capable of waking up devices in a sleep mode. However, these mechanisms typically rely on technologies such as Near-field communication (NFC) and Radio-frequency identification (RFID) to facilitate the wakeup techniques. Unfortunately, these techniques are expensive both in terms of increased production costs and increased size or printed circuit board (PCB) area. Moreover, communications using NFC and RFID technology can compromise performance of the underlying RF antenna on the low-power device.

 Not merely the horizontal bicycle-built-for-two - type color laser printer but besides a monochrome laser printer suffer from the same problem when a develop agent storage bedroom is locate above a developing bedroom. 
 Since the problem of deterioration of a developing agent is caused by subjugate the developing agent to sliding friction, the problem normally can occur over developing devices in which a evolve agent is charged through clash charging. In the event that the develop agent is devolve, phenomena such as a reduction in fluidity due to the embedment of externally add agents which are externally added to the developing agent and a decrease in charge quantity due to a reduction in charging function are generated. This phenomena may cause rough and scattered impression and in bad case, backdrop fogging, on an prototype formed on a recording sheet. 
 When a fresh and non - deteriorated explicate agent is added to the deteriorated developing agent whose charge function is reduced, a charging failure is caused in the deteriorated developing agentive role depending upon conditions, and this may cause a situation in which the background fogging is worsened. Factory (or factory line) program low - power devices such as wearables, medical device, and the like, requires bidirectional communication between the programming device and the low - power device(s) being programmed. The low - power device typically have a build - in radio receiver frequency (RF) radio for transferring data. For example, many gloomy - power device in the healthcare, fitness, security, and aesculapian industries utilize Bluetooth low energy (BLE or Bluetooth Smart) radios to transfer data. Many of these devices such as, for example, medical devices, have non - replaceable battery with limited lifetime capacitance. Prior to deployment of these devices, but before and after factory programming, it is much desirable to disable the RF radio, e.g., put the device in a rest mode, to avoid current leakage which can significantly lower the shelf life of the device. 
 There are diverse mechanism capable of waking up devices in a sleep mode. However, these mechanisms typically trust on technologies such as Near - field communication (NFC) and Radio - frequency identification (RFID) to facilitate the wakeup techniques. Unfortunately, these techniques are expensive both in terms of increased output costs and increased size or printed lap board (PCB) area. furthermore, communications using NFC and RFID technology can compromise performance of the underlying RF antenna on the low - power device.
