Now the boundaries between A3 copiers and A4 all-in-ones are becoming more and more blurred. Thousands of budgets are required to get a copy of the office's documents, buy A4 all-in-ones, and buy A3 copiers. How do you choose this time?
In this article, we combine the experience of the past and test the experience of the A4 all-in-one. Let's talk about the HP M433a 'Light Printing' copier. After reading it, there will be an answer.
A3 copier and A4 machine
HP M433a is delivered to the office from the logistics. It is obviously larger than the A4. Unpacking and installing one person, the best two people take the handle. The copier packing box clearly marked out of the box, on both sides of the The two parts of the forced area lift one side and lift it out of the box.

HP's so-called 'light text printing' is low threshold, easy to use. This M433a copier is the most basic model, using USB connection printing and scanning, no automatic two-sided printing, ADF document feeder, scanning and copying are the most Basic configuration.
The operation panel is a four-line text LCD screen and navigation keys. There are also copy, scan, ID quick copy, zoom, paper, density, menu and other function keys and numeric keypad. The power/start key indicates the copier's running status and can be waked up with a key, which is a practical energy-saving function.

Unpacking the copier takes a little longer. The imaging drum removes the protective layer insertion slot, and the power and control interface is inserted into the slot. You also need to install two screws with a Phillips screwdriver to fix the imaging drum. Insert the cartridge into the slot, Close the side cover and front cover.

Note here that the screw bag is stuck on the copier bag to avoid accidentally throwing the bag away from the screw. The screw must be tightened to secure the imaging drum to avoid loosening of the image drum during the future transport. Next article, we take a closer look at the consumables of the HP M433a copier.
High-capacity consumables and high loads
HP M433a supplies are photosensitive drums and toner cartridges. 57A photosensitive drum nominal life of 80,000, standard loading toner cartridge 56A nominal capacity of 7400 pages. This print far beyond the low-speed A4 black and white laser MFP, supplies More durable, reduce the frequency of replacement.
There is also a high-capacity toner cartridge 56X with a nominal capacity of 12,300 pages. This print volume is almost unattainable in the mid-to-low-speed A4 monochrome laser MFP.

The recommended monthly print capacity of the HP M433a copier is 2,000 pages, and the maximum monthly print load is up to 40,000 pages, which is far beyond the mid-low speed A4 monochrome laser machine. In addition, the design life of the A4 monochrome laser machine at the same speed is usually 100,000. Pages to 200,000 pages, while entry-level A3 copiers have a design life of 400,000 to 600,000 pages. The HP M433a is more durable and more durable.
In other words, the HP M433a's consumables throughput, use load, and design life are far beyond the mid-to-low-speed A4 monochrome laser machine. In the case of large print, centralized printing and copying, priority is given to entry-level HP M433a. A3 copier.
Speed Test Basic Performance
Look at HP's M433a for copy, scan, and print performance. Single-page copying is faster because copying is done earlier to wake up the dormant copier. Preheating is done when the document is placed. 1 page copied to 9 pages, first page The output is also faster; removing the top page time conversion yields a copy speed of 20.0 ppm, which is consistent with the nominal value, which is a basic copying performance.
The scanning time is as follows. Because it contains the time for transferring data between the PC and the copying machine, it is slightly slower than the copying speed, but it is still relatively fast. Although it is a black-and-white copier, the HP M433a still supports full-color scanning.
Single-page document printing is also faster, Excel, PDF, TXT files can be quickly printed out, and the response is faster. Multi-page document printing, converted print speeds get Excel at 19.6ppm, 20.3ppm, 20.4ppm, with nominal 20ppm printing The speed is basically the same.
In general, the HP M433a entry-level copier has a fast response, a performance basis, and the copying and printing speed is consistent with the nominal value of 20 ppm. Multi-page document scanning and copying may be tedious. If you need to use this, you may choose a higher-order HP M436nda. There is a lot of convenience for ADF document feeder.
Output quality
Black and white documents and photocopies, copies are clearer and easier to read than the printed text, the blackness is even, the darkness of the image is lower, and the background color is desalinated to ensure the clarity of the main content. This effect is also less when copying. Use some toner.

The white and reversed English letters are also similar. The letters are sharp and sharp from 6p. The blanks of the black proofs with 6p and above are clear and the borders of the background color are clear. The strokes are not invaded by ink. The background is black and even. The print quality is good.

In a comprehensive view, the HP M433a copier has good copying, scanning and printing effects. The image quality of the toner cartridge is good, and the printed output has a good sense of reading. It can handle the black-and-white documents, graphics, forms, charts, bills, and documents used in the office.
Power Test Energy Saving Effect
In the past we have tested the power consumption of hundreds of A4 laser machines. What is the current A3 laser photocopying opportunity? Look at the HP M433a print process power curve.
In the hibernation state, the measured instantaneous power is 0.00 watts, 0.56 watts, alternating between the two, the power is very low. Most of the components of the copier are powered off, only the wake-up circuit has intermittent pulse currents, this energy-saving design in a few A4 Laser machine also exists.
↑↑↑ Instantaneous power in hibernation
After the print starts, the fuser unit is rapidly heated to the fixing temperature, and the power quickly reaches a peak of 806.20 W. Since it is an A3 machine, the fixing unit is also larger than the A4 laser printer, and the peak power is also higher.
峰值Print process peak power
With the continuation of the printing process, the power is significantly reduced, and the zigzag power curve indicates that the fixing unit is heated intermittently to maintain the fixing temperature. The average power of the printing process is calculated to be 471.7 watts, which is less than four hundred watts compared to A4 laser printing. Higher print power.
After the printing was completed, the copier was put into standby mode, and the instantaneous power was 8.86 watts and 8.85 watts, which was a relatively high level. Soon, the still photocopier was put into a sleep state, and the instantaneous power was also reduced to 2.22 watts, 0.92 watts, and Restore to the initial sleep state. Short standby time, so power consumption is not high.

In general, the HP M433a copier has very low power consumption, good control of print and standby power consumption, and better energy efficiency in long-term use. This is one of the core points of HP's 'light text' concept.
Evaluation summary:
To sum up, about 4000 yuan HP M433a entry-level A3 black and white copiers, durable supplies, high load, support for more types of printing media, energy-saving effect is good, cheap printing and writing; same price of the middle of the A4 monochrome laser machine, Faster, higher configuration, network-sharing printing and scanning, more convenient handling of multi-page files.
On the other hand, HP M433a features and configuration basis, performance basis, inconvenient for many people to share; A4 monochrome laser machine with the same price, consumables print and load worse, can not handle media over A4 format, Wen Yin The cost is higher.
If you spend the same amount of money, buy two or three entry-level A4 laser machines, we do not recommend. The higher the concentration of printing equipment, the better, the dispersion is not conducive to equipment management and maintenance, failure rate will be higher.
Therefore, in the case of large quantities and large file types, the HP M433a A3 copier is preferred, and the stability and convenience brought by Hewlett-Packard's 'Light Paper Printing' are harvested.
