Laserjet 4000
Q. True or False: This unit has a swing plate assembly.
False
CORRECT
Laserjet 4600
Q. True or False, Does the tray 1 and tray 2 assembly share a common pickup assembly?
False
Incorrect, they do share the same pickup assby.
Laserjet 2430
Q. True or False: The fuser is given power by the high voltage power supply.
True
Not sure about technical answer, but in general fusers are always powered by DC voltage, which is not high voltage so I would guess no unless DC and HV are on the same board.
Q. Do tray 1 and tray 2 share a pickup assembly in this unit?
False
Correct. Neither has an assembly per se. Each is just a shaft with a pickup roller and a solenoid.

Laserjet 4200
Q. Does this unit have 2 power supplies?
False.
Power Supply and DC Controller PCA.
You are correct that it has a PS and a DC Controller PCA.
Q. Does tray 1 and tray 2 share a common pickup assembly?
True.
Incorrect. It has a tray 1 pickup assembly and there is a totally separate pickup drive assembly for tray 2.
Laserjet 4350
Q. Does this unit have 2 power supplies?
True.
Power Supply and DC Controller PCA.
It is similar to 4200. If the DC Controller is considered power supply, than this is correct and your answer to the 4200 is incorrect. Instead of the true false answer, if I were a prospective employer I would focus more on the fact that you knew there was a power supply and also a DC Controller.

Q. Does tray 1 and tray 2 share a common pickup assembly?
True.
Incorrect. Same setup as a 4200.

Laserjet 4015
Q. How many power supplies does this unit have?
Two. 24 VDC & 3.3 VDC
It has a DC Controller and a power supply.

Mechanical aptitude and an understanding of how printers actually work is more important than trivial details about printers IMHO. Two of our best techs would have been guessing on every one of those questions when they were hired.
Good luck!
