It appears that the issue you are facing is related to the excessive return statements within the if statement block mentioned.

Here is the original block of code...

if (!inputs.job.isAnalysisComplete) {
    return;
    actions.job.chargeToPersonalAccount();
    return;

    if (inputs.job.totalPages < 10) {
        actions.job.chargeToSharedAccount(ADM-3900);
    } 
} 

A revised version of this block could look like this...

/*If there is no print analysis information, exit the function immediately!*/
if (!inputs.job.isAnalysisComplete) {
    return;
} 

/*For jobs with less than ten pages, charge the shared account. Otherwise, charge the personal account.*/
if (inputs.job.totalPages < 10) {

    /*Also, it is advisable to include quotes around ADM-3900 as it appears to be a string reference.*/

    actions.job.chargeToSharedAccount("ADM-3900");
} else {
    actions.job.chargeToPersonalAccount();
}

Please note that this is my best interpretation without prior knowledge of Papercut software.

After reviewing your objective, I will implement the following modifications to your code:

/*
* Automatically redirect large print jobs
*
* Users with print jobs exceeding a certain page count will have their
* print jobs redirected to another printer or virtual queue.
* This can optimize printing by directing large jobs to more efficient printers.
*/

// Define charge limit for ADM-3900 account.

var ADM_3900_CHARGE_LIMIT = 10;

// Specify redirection settings for larger print jobs.

var REDIRECT_PAGE_LIMIT = 50;
var REDIRECT_PRINTER = "Copier - Color";

function printJobHook(inputs, actions)
{    
    /*
    * This print hook requires access to all job details.
    * If full job analysis is not completed yet, this function will return.
    * Only metadata like username, printer name, and date are available initially.
    *
    * Refer to documentation for further clarification.
    */

    // Verify if job analysis is complete.

    if (!inputs.job.isAnalysisComplete)
    {
        // No detailed job information available yet.
        // XXX: Return a distinct value prompting the client to call this method again after a few seconds when analysis is finalized.
        return false;
    }

    // For print jobs below ADM_3900_CHARGE_LIMIT, charge to shared account.

    if (inputs.job.totalPages < ADM_3900_CHARGE_LIMIT)
    {
        // Charge to firm non-billable account (ADM-3900).
        actions.job.chargeToSharedAccount(ADM-3900);

        // Successful execution.
        return true;
    }

    // For jobs above ADM_3900_CHARGE_LIMIT, charge to personal account.

    actions.job.chargeToPersonalAccount();

    // Determine if job needs to be redirected to more efficient printer.

    if (inputs.job.totalPages > REDIRECT_PAGE_LIMIT)
    {
        /*
        * To bypass release queue at original printer, use actions.job.bypassReleaseQueue().
        * Redirect job to high-volume printer if it surpasses page limit.
        * Option to hold job at new printer's release queue is available with {allowHoldAtTarget:true}.
        */

        actions.job.bypassReleaseQueue();
        actions.job.redirect(REDIRECT_PRINTER, {allowHoldAtTarget: true});

        // Notify user about automatic job redirection.

        actions.client.sendMessage(
            "Print job exceeded " + REDIRECT_PAGE_LIMIT + " pages and was redirected to printer: " + REDIRECT_PRINTER + "."
        );

        // Log job redirection in application log.

        actions.log.info(
            "Large job redirected from printer '" + inputs.job.printerName + "' to printer '" + REDIRECT_PRINTER + "'."
        );
    }

    // Successfully complete process.
    return true;
}

Solution Code for Achieving a Specific Goal:

/*
* Automated redirection of large print jobs
* 
* Print jobs exceeding a certain number of pages are automatically redirected to another printer or virtual queue,
* streamlining the printing process and optimizing resource allocation.
* This functionality enables the rerouting of lengthy print jobs from slower or costly printers to more efficient alternatives.
*/

function implementPrintJobRedirection(inputs, actions) {

  /*
  * This print hook requires access to comprehensive job details.
  * Exit function if complete job analysis is not yet available.
  * Initially, only metadata such as username, printer name, and date are accessible.
  *
  * Refer to documentation for detailed clarification.
  */
  if (!inputs.job.isAnalysisComplete) {
    // Job details pending completion, exit function.
    return;
  }
  /*
  * NOTE: Ensure compatibility between the high-volume printer and the source printer.
  *       Use the same printer language (e.g., PCL or Postscript).
  *       For virtual queues, all printers in the queue must support the same printer language.
  */

  if (inputs.job.totalPages < 10) {
    // Less than 10 pages - charge to the shared non-bill account
    actions.job.chargeToSharedAccount("ADM-3900");
  }
  else{
    // Job exceeds 10 pages - trigger cost center popup

    actions.job.chargeToPersonalAccount();
    // Account Selection will still display

    var LIMIT             = 50; // Redirect jobs over 50 pages.
    var HIGH_VOL_PRINTER  = "Copier - Color";

    if (inputs.job.totalPages > LIMIT) {
      // Job surpasses 50 pages

      /*
      * Utilize actions.job.bypassReleaseQueue() to skip the release queue
      * of the original printer and expedite printing at the target device.
      */
      actions.job.bypassReleaseQueue();

      /*
      * Since the job surpasses our page threshold, redirect it to the specified high-volume printer
      * while notifying the user.
      * To allow holding the job at the designated hold/release queue of the high-volume printer,
      * set "allowHoldAtTarget":true.
      */
      actions.job.redirect(HIGH_VOL_PRINTER, {allowHoldAtTarget: true});

      // Inform the user about the automatic redirection of their print job.
      actions.client.sendMessage(
        "The print job exceeded " + LIMIT + " pages and has been directed to " 
        + "printer: " + HIGH_VOL_PRINTER + ".");

      // Log the redirection of the job in the application log.
      actions.log.info("Large job redirected from printer '" + inputs.job.printerName 
                     + "' to printer '" + HIGH_VOL_PRINTER + "'.");
    }
  }
}

Your input is converted to:

if(jobs > 50) redirect to Copier-Color
elseif(jobs > 10) cost center popup
else charge automagically

This can be translated into JavaScript as follows:

const   LIMIT_10            = 10,
        LIMIT_50            = 50,
        HIGH_VOL_PRINTER  = "Copier - Color";

function printJobHook(inputs, actions) {
    if (!inputs.job.isAnalysisComplete)
        return;

    if (inputs.job.totalPages > LIMIT_50) {
        actions.job.bypassReleaseQueue();
        actions.job.redirect(HIGH_VOL_PRINTER, {allowHoldAtTarget: true});
        actions.client.sendMessage(
          "The print job was over " + LIMIT + " pages and was sent to " 
          + " printer: " + HIGH_VOL_PRINTER + ".");

        actions.log.info("Large job redirected from printer '" + inputs.job.printerName 
                         + "' to printer '" + HIGH_VOL_PRINTER + "'.");
    }else if (inputs.job.totalPages > LIMIT_10) {
        actions.job.chargeToSharedAccount();
    }else{
        actions.job.chargeToPersonalAccount(ADM-3900);
    }
