Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a circuit adjustment method for incorporating an image bearing member, that is, a photoreceptor, into an image recording apparatus.

[Conventional technology]

In an image recording device that uses electrophotography to form an electrostatic latent image on an image bearing member, that is, a photoreceptor, and transfers the developed toner image to recording paper, the photoreceptor is usually a 70-page recording device. The structural members are formed into a drum or belt shape, such as an aluminum alloy base coated with selenium vapor deposited or a synthetic resin base coated with an organic semiconductor.

This photoreceptor reaches the end of its lifespan after recording a certain number of sheets, and must be replaced with a new one.

Also, there are various types of photoreceptors with various performances, and each type has a specific sensitivity and acceptance voltage, and even photoreceptors of the same type have some variation depending on the K. The operator selects and adjusts the amount of light, charging current, grid voltage, and developing bias when replacing or installing a photoreceptor.

[Problem that the invention seeks to solve]

As mentioned above, when replacing a photoconductor in an image recording device such as a general electronic copying machine, service personnel adjust the scales of the light intensity, charging current, grid voltage, and developing bias of the main body according to the characteristics of the photoconductor. I'm making adjustments.

In addition, the cartridge type has a cleaner, electrode,
In some cases, there are units that include the developing device and are made into a unit that can be replaced by the user, but there are also units that incorporate variable resistors and switches that change the amount of light.

(However, such operations require skill, are cumbersome, and take time to make adjustments, and there is also the fear of accidentally setting the wrong data.

[Means for solving problems]

This problem is solved by [a mark is provided on the image recording device of the image bearing member which is an image recording component of the image recording device, and when the image bearing member is incorporated into the recording device, the recording device detects the mark. A method for adding image carrier information to an image recording apparatus, characterized in that performance information of the image carrier is read from a button and a suitable circuit of the recording apparatus is selectively configured.

〔Example〕

FIG. 1 shows the configuration of an image forming apparatus according to the present invention.
A laser beam emitted from a semiconductor laser drive circuit (not shown) is shaped on the way and enters a polygon 11 of an optical system 10 in the apparatus, is reflected by a mirror surface of the polygon 11, and is then reflected by an fθ lens 12, a cylindrical lens 13, and a mirror. The light is projected onto the circumferential surface of the photoreceptor 2o through the light beam 14.

The photoreceptor 20 is a belt-shaped photoreceptor with an end, and is rotated and conveyed counterclockwise on the upper surface of a conveyor table 24 by three photoreceptor support rollers 21, 22, and 23K. , and the peripheral surface thereof is charged with a charge by the charged transfer electrode 25, so that an electrostatic latent image is formed by an electrostatic signal by receiving the laser beam as described above. .

Subsequently, the photoreceptor 20 is supplied with toner by the developing roller 26 of the developing device to turn the electrostatic atom on the circumferential surface into a toner image, and the photoreceptor 20 is rotated below the conveyance table 24 and conveyed counterclockwise. However, at the same time, one sheet of recording paper is fed into the device by the operation of the paper feed roller 31 from the automatic paper feeder 30 attached to the device and linked, and the sensor 41 that detects the leading edge of the recording paper is fed into the device. The second paper feed roller 240 starts rotating and further feeds the recording paper, and the second paper feed roller 40 is stopped by the action of the sensor 42 that detects the leading edge again, and the timing with the toner image is adjusted. The rotation is then restarted and the conveyance of the recording paper continues.

The photoreceptor 20, in which the recording paper is integrated, transfers the toner image onto the recording paper at the charged transfer pole 25, separates the recording paper, and removes the remaining toner by exposing the entire surface to a laser beam to eliminate the charge. First, the adhesion force is weakened by the auxiliary cleaning means 27, and then the cleaning action of the developing roller 26 removes the toner. The auxiliary cleaning means 27 is a Darashi-like device made of insulating fibers, and is of a type that does not interfere in any way with the potential of the electrostatic latent image formed in the preceding cycle.

In this way, the photoreceptor 20 is charged again at the charged transfer pole 25 and moves on to the next cycle of rotation and conveyance to form a new electrostatic surface, but at the same time, the recording material that has been transferred with toner particles during that period is The paper is peeled off from the surface of the photoreceptor 200 by the photoreceptor support roller 21 and fixed p-
La 50 Separation claw 5 after melting and fixing toner in VC
1, the paper is guided to the discharge paper p-252, the residual potential is removed by the static elimination brush 53, and the discharged paper is discharged from the apparatus.

Here, the support rollers 21, 22, and 23
The photoreceptor 20, which is installed on the upper surface of the 4 so as to rotate counterclockwise, constitutes a drawer unit 29 together with the photoreceptor 26, and is designed so that it can be pulled out from the main body via a drawer guide 28. Km to make it easier to process
It is designed so that the light body 20 can be replaced or repaired relatively easily.

Furthermore, as shown in FIG. 2, this photoreceptor 20 has a carbon conductive layer 61 provided outside the effective recording area of the photoreceptor ◇The conductive layer is provided to maintain a 7-space with the main body. However, a sign 62 is provided by printing or pasting a sticker on this part. This sign 62 is preferably a bar food or similar. Then, as shown in FIG.
I Read. Here, since the conductive layer portion 61 is carbon-based, its reflectance is small, so that reading errors of the mark 62 are completely inconceivable. The data entered in the label 62 here are photoreceptor characteristics, sensitivity and accepted voltage.

A parity pit is provided in the marker 62 as shown in FIG. 4 in order to further improve the reliability of the read signal.

The system uses a system that compares this bit with the sum of other bits, checks for reading errors, and rereads if there is an error.

The read data may be read in the same way for each print, or it may be left in memory without doing so and updated only when the photoreceptor is replaced.
In this embodiment, the latter is adopted.

In Figure 4, the sign is represented by five white or black bars of the same width.From the left, there is a reference mark, and the next three bars represent the performance information of the photoreceptor. If detected, eight levels of data can be read. The bar on the right side is the parity bit. If it is reflected, it is read as 1, and if there is no reflection, it is read as 0. In this example, if the 4-bit binary number, including the 3-bit performance information and 1-bit parity bit, is converted into a decimal number and is an even number, it is determined that it has been read correctly, and if it is an odd number, it is determined that it has been read incorrectly. It is determined that the detection has occurred, and re-detection is performed.

The above-mentioned reference mark serves both as a reference position of the photoconductor and also to detect the position of the joint, and is also used to prevent the joint from entering the effective image recording area in the photoconductor feeding direction. In order to further improve performance, it is possible to increase the number of bars or to combine the widths of black and white bars.

Although the above embodiments used a belt-shaped photoreceptor, it is of course possible to implement a method using a cylindrical photoreceptor. The marker 62 may be attached at a location outside the iiijgI recording area of the photoreceptor, but it is even better if the location is on a conductive surface. This is because there is a possibility that toner may accidentally adhere to the sign surface and cause malfunction.Similarly, the K8!1162 itself is also preferably conductive.Black marks are placed on the photoreceptor surface, which has a high reflectance. If you are attaching a label, you can reverse the reading, i.e., set the black mark to 1.Also, when attaching a label to a highly reflective conductive layer such as a resin containing full mini neem powder, use a black mark. IIC.

When the base of the photoreceptor is made of an aluminum alloy and is conductive, there is no need to provide a conductive layer, and a black mark with low reflectance is placed outside the image recording area as the HR.

If the belt-shaped photoreceptor has a transparent conductive layer as shown in FIG. 5, it is possible to place marks on the back side of the photoreceptor.

In addition, as shown in Figure 6, in the case of a busy drum, when a full mini tube, a -mu tube, or a plastic film on which one side is conductively treated is used as the support for the photoreceptor, the photoreceptor may not be coated outside the image recording area. When the section 63 is provided, it is desirable to add Ks fiber to that section.

Furthermore, in the case of a drum, the side surface 64KI as shown in Figure 6
I1m! It is also possible and effective.

When the photoreceptor is attached to the main body of the image recording apparatus in this way, the performance information of the photoreceptor is detected, and in response to the signal, a predetermined amount of light, charging current, grid voltage, and bias are programmed into the main body. A transistor switch automatically operates on the voltage, and a switching compatible circuit is formed.

〔Effect of the invention〕

According to the present invention, the unique performance of each photoconductor is detected by the image recording device main body, which is a marker attached to the photoconductor, and circuit adjustment is made by matching the performance data when installing or replacing the photoconductor to the image recording device main body. K so that work can proceed automatically without the operator being aware of it.
This greatly simplifies the adjustment work that hitherto required skill, eliminates the possibility of erroneous adjustment, and provides a highly reliable image recording device.
