Xerox 4045 laser printer L2 and L3 errors

I used this for a while with excellent results until I got L2 or L3 errors. Haven't been able to find a Maintenance manual. Can you help please?

    Can't see how to reply properly to SeekPCRepair's note, so adding as addendum this post!

    I actually bought the 4505 (I think) manual listed here, but nothing for the quite different 4045/4046 is shown.

    I think Xerox offer one at several hundred dollars! If any Xerox engineer out there can help, or you have a service/technical/maintenance manual It would be a real service. One expert respondent advised they'd thrown out all their 4045s because of the cost and problems of maintenance, for which they couldn't get reasonable help. These laser printers are really superb output, with potentially long life, but need support.

An L2 code indicates that the ROS PWB has failed to detect a start of scan signal. A L3 is the laser beam will not go on. In english this means that the laser has failed or power going to it has failed. As a former Xerox tech that worked on this model unless you have a spare 4045 for parts it is time for a new printer. You can check all the connections to the laser but it more than likely has a bad laser assembly, (or parts of the assembly-polygon motor,ROS pwb, laser diode) or IOTC pwb. If you are not familiar with servicing laser printers to not attempt to repair this yourself. Working on this laser printer can be hazardous. You cannot see the laser beam and could cause permanent eye damage. It also has high voltages in this printer. Be careful and hope this helps.

From the manual I have the 4045 LASER CP MODEL 150 REFERENCE MANUAL all it says about either L2 or L3 is that they are "Scanning failure"s and said to look at the User manual "Operating the 4045" section
in the back of that the only mention I found was that L2, L3, and L5 are "illuminator malfunctions."

Hi Derek:

I checked my stash and I don't have a manual for this specific model. However, you can purchase a service manual for $11.99:

Zdt12011fa dishwasher is built in and the flood alarm is in operation - how do I reset?


First you need to remedy failure or any leakage than reset appliance.
Under Reset I mean to delete all alarm stored in memory.

1. Turn off the dishwasher.
2. Press and hold S1 while switching on the dishwasher. Keep
holding the Program button until:
- LED L1 blinks, L2 and L3 is on
- Release S1
3. When L1 is blinking, L2 and L3 is on, press the S1 before L2 and
L3 is turned off.
- LED L2 is blinking, L1 and L3 is turned on.
4. Wait till L1 and L3 is turned off, then press S1
- All used LEDs flash 5 seconds on 1 second off repeatedly.
- If buzzer is equipped, it beeps for 5 seconds
- The alarms saved in the memory are erased
5. Switch off the appliance.

Can't get rid off L2 message on the recorder.


If I'm understanding this as what I think it is - that's not an error message at all! It's the input your recorder is currently set on (I'm talking about the "L2" shown in the right side of the LED display when the unit is powered on, where the channel number would usually be.) In order to change that, you have to open the bottom flap on the front of the machine (or slide open the remote bottom for the record controls to be exposed,) and press the "Input Select" button twice until it cycles through L3 and ends on whatever channel you last left it on - I think it defaults to 100 if the power has been interrupted. When you press this button after that, it would cycle through "L1", "L2", "L3", and the channel input (or coaxial cable input, to be exact), as expected. I know of no other "L2" message you might be speaking of. If I'm incorrect on this, I apologize. But I hope I'm not and that this simple issue is all that is causing you a headache! Good luck! And by the way, "L1,2, & 3" are the RCA/S-Video inputs on the back (L1 and L3) and on the front (L2) of your machine for various things you might plug in (video cameras, etc.) Note: For L1 and L3 ONLY, you have to go into setup to select whether you will be using the RCA yellow or S-Video jack on the back of the machine for the video of that particular input (with no bearing on the RCA audio jacks for that particular input - they're always used...) - the front L2 input evidently selects on its own between S-Video and the RCA yellow plug, based on which plug has something plugged in. I haven't tested to see which it will select if they are both occupied with a plug on L2. I don't mean to treat you like an idiot -- please don't take it that way - but I don't know how much you know about electronics, and IF I'm right about this whole thing, then I'm sort of assuming you aren't too familiar with them. In either case, please know that I mean well, and any information that you already know, just overlook. Thanks, and again, good luck!

My calculator is TI-83 plus. I get Err: data type every time I want to use lists to calculate something. For example I enter 5,10,15,20,25 in list 1 and 5,5,5,5,5 in list 2. Then in list 3 I type L1/L2,...


You can't manipulate lists like that.

{5,10,15,20,25}[STO>]L1
{5,5,5,5,5}[STO>]L2

These will input your lists properly. I'm not sure what you're trying to do, but if you're just trying to divide every entry in L1 by 5 and store it in L3, you could accomplish that with:

{5,10,15,20,25}[STO>]L1
L1/3[STO>]L3

Also, this page gives a lot of helpful tips on using lists on a TI-83.

Hope this helps!

In my precal class we are studying trigonometry graphing. On my calculator I made 3 lists L1, L2, and L3 when I go to graph and regulate the equation it only regulates the equation for both L1 and L2....


I do not know what you mean by regulate, but if you want to perform a regression analysis using data from L1 and L3, all you have to do is to specify the lists to be used.
For example if you have to perform QuadReg on L1,L3,
  1. Press [STAT] button,
  2. then Right Arrow to select CALC(ulate)
  3. then [5:QuadReg]
  4. The command QuadReg echoes on main screen as QuadReg .
  5. At this point press [SHIFT][1] to select (L1), then [COMMA], then [SHIFT][3] to select (L3) , and finally [ENTER].
  6. The result will be displayed after regression is performed.
  7. If you want to save the regression equation in Y1 so as to graph it over the scatter plot you enter QuadReg L1, L3, Y1 [ENTER]

I have data entered in L1 and L3. And I want to take the log of L3 in L2. But after I do that it gives me an error. How can I fix this.


Hi,
If the data in your L3 list contains only positive numbers there is no reason why you should not be able to calculate the log of the list and store that in L2.
  1. You open the list editor, [STAT][1:Edit]
  2. Use arrows to position the cursor on an element of L2.
  3. Use UpArrow to highlight the L2 heading (at the top of the list) and press ENTER.
  4. The data entry line will show L2= ..
  5. Erase anything that may be on the L2 entry line and type in
  6. [LOG] [2nd] [3] (L3) to enter the L3 identifier inside the log (
  7. Close the right parenthesis. Screen shows L2= log(L3)
  8. Press [ENTER]
  9. The L2 list will be populated with the logs of the elements of L3.
Hope it helps

The display screen reads "L3"


that is related to the scanner. Lamp, or cable, and to be honest, it would be much less problem to replace the printer. That is a very hard machine to service and that is a difficult problem and can be very expensive to repair.
